They comprise about 10% of all the salient features of various types of gallstones are gallstones blood pressure log excel purchase altace 10mg on-line. They constitute about 10% of all (cholesterol blood pressure jogging buy 5 mg altace otc, bile pigment or calcium carbonate) and outer gallstones blood pressure 6050 buy altace discount. They are further divided into 3 types according shell of mixed gallstone; or a mixed gallstone nucleus with pure to the component of bile forming them heart attack 34 years old order altace us. It may result in deposition of cholesterol and may be diagnosed by chance during investigations for within the mucosal macrophages of the gallbladder some other condition (silent gallstones hypertension powerpoint altace 10 mg lowest price. The future course in producing cholesterolosis which is an asymptomatic condition such asymptomatic silent cases is controversial blood pressure negative feedback order altace online from canada, most (Fig. Pure cholesterol stones are radiolucent but 10surgeons advocating cholecystectomy while physicians 20% of them have calcium carbonate in them which renders advising watchful waiting. They have mulberry like cholecystitis is well known but it is not certain which of the external surface. Calcium colic precipitated by fatty meal, nausea, vomiting, fever carbonate gallstones are usually multiple, grey-white, small alongwith leucocytosis and high serum bilirubin. They, too, do not produce any change in extrahepatic biliary passages and the small bowel, or less the gallbladder wall. Mixed gallstones are the most common gallstone in the common bile duct frequently develop pain (80%) and contain more than 50% cholesterol monohydarate and obstructive jaundice. Fever may develop due to bacterial plus an admixture of calcium salts, bile pigments and fatty ascending cholangitis. The condition usually begins with obstruction, passed in the faeces without causing symptoms. Based on the initiating mechanisms, intestinal obstruction called gallstone ileus. Obstruction results in distension of the gallbladder followed by acute inflammation which is initially due to chemical irritation. In such cases, a variety of causes have been assigned such as previous nonbiliary surgery, multiple injuries, burns, recent childbirth, severe sepsis, dehydration, torsion of the gallbladder and diabetes mellitus. Rare causes include primary bacterial infection like salmonellosis and cholera and parasitic infestations. Except for the presence or absence of calculi, the two forms of acute cholecystitis are morphologically similar. The serosal surface is coated with fibrinous exudate with congestion and haemorrhages. The wall of the gallbladder is thickened and the lumen is packed with well-fitting, multiple, multi-faceted, mixed gallstones. Grossly, the gallbladder exudate and the condition is known as empyema of the is generally contracted but may be normal or enlarged gallbladder. The wall of the gallbladder is thickened which Microscopically, wall of the gallbladder shows marked on cut section is grey-white due to dense fibrosis or may inflammatory oedema, congestion and neutrophilic be even calcified. There may be frank abscesses in the wall and thickened, or flattened and atrophied. The lumen gangrenous necrosis with rupture into the peritoneal commonly contains multiple mixed stones or a combined cavity (gangrenous cholecystitis. Thickened and congested mucosa but occasionally of either type have similar clinical features. Penetration of the mucosa deep into the wall of the irritation such as guarding and hyperaesthesia. The gallbladder up to muscularis layer to form Rokitanskygallbladder is tender and may be palpable. Early cholecystectomy within the first consisting of lymphocytes, plasma cells and macrophages, three days has a mortality of less than 0. Variable degree of fibrosis in the subserosal and attacks and adhesions is avoided. There is almost constant association of Porcelain gallbladder is the pattern when the chronic cholecystitis with cholelithiasis. The association of chronic Acute on chronic cholecystitis is the term used for cholecystitis with mixed and combined gallstones is virtually the morphologic changes of acute cholecystitis always present. However, it is not known what initiates the superimposed on changes of chronic cholecystitis. Generally, the patienta fat, fertile, repeated attacks of mild acute cholecystitis result in chronic female of forty or fifty, presents with abdominal distension or cholecystitis. There is penetration of epithelium-lined spaces into the gallbladder wall (RokitanskyAschoff sinus) in an area. Mononuclear inflammatory cell infiltrate is present in subepithelial and perimuscular layers. Biliary colic may and cholecystitis, though there is no definite evidence of occasionally occur due to passage of stone into the bile ducts. Cholelithiasis and cholecystitis are Cholecystography usually allows radiologic visualisation of present in about 75% cases of gallbladder cancer. A number of chemical carcinogens structurally similar to naturally-occurring bile Benign tumours such as papilloma, adenoma, adenomyoma, acids have been considered to induce gallbladder cancer. Adenomyoma is more common benign tumour than the higher incidence of gallbladder cancer. All these tumours resemble their counterparts in morphology elsewhere in the body. Japanese immigrants and Native Americans Carcinoma of the gallbladder and carcinoma of the bile ducts of the South-Western America have increased frequency and ampulla of Vater are among the more frequent malignant while American Indians and Mexicans have lower incidence. Patients who have undergone previous surgery on the biliary tract have higher incidence of Carcinoma of the Gallbladder subsequent gallbladder cancer. Patients with inflammatory Primary carcinoma of the gallbladder is more prevalent than bowel disease (ulcerative colitis and Crohns disease) have other cancers of the extrahepatic biliary tract. It may remain undetected until the time it is widely fundus, followed next in frequency by the neck of the spread and rendered inoperable. They may be papillary or infiltrative, well-differentiated or poorly-differentiated. About 5% of gallbladder cancers are squamous cell carcinomas arising from squamous metaplastic epithelium. A few cases show both squamous and adenocarcinoma pattern of growth called adenosquamous carcinoma. Carcinoma of the gallbadder is slow-growing and causes symptoms late in the course of disease. Quite often, the diagnosis is made when gallbladder is removed for cholelithiasis. The symptomatic cases have pain, jaundice, noticeable mass, anorexia and weight loss. In such case, the growth has usually invaded the liver and other adjacent organs and has metastasised to regional lymph nodes and more distant sites such as the lung, peritoneum and gastrointestinal tract. This is an infrequent neoplasm but is more common than the rare benign tumours of the biliary tract. Infiltrating type appears as an irregular area of diffuse diseases of the biliary passages, it is more common in males thickening and induration of the gallbladder wall. Fungating type grows like an irregular, friable, with a number of other conditions such as ulcerative colitis, papillary or cauliflower-like growth into the lumen as well sclerosing cholangitis, parasitic infestations of the bile ducts as into the wall of the gallbladder and beyond. Extrahepatic bile duct carcinoma may arise anywhere in the biliary tree but the most frequent sites, in descending order of frequency, are: the ampulla of Vater, lower end of common bile duct, hepatic ducts, and the junction of hepatic ducts to form common bile duct (see Fig. Grossly, bile duct carcinoma is usually small, extending for 1-2 cm along the duct, producing thickening of the affected duct. Histologically, the tumour is usually well-differentiated adenocarcinoma which may or may not be mucinsecreting. Obstructive jaundice is the usual presenting feature which is characterised by intense pruritus. The lumen of the gallbladder contains irregular, friable papillary growth arising from mucosa (arrow. The human pancreas, though anatomically a single organ, Two multi-faceted gallstones (mixed) are also present in the lumen. The endocrine part of the gland viscidosis) and associated with increased concentrations of 645 is dealt with in Chapter 27 while the exocrine gland is electrolytes in the eccrine glands. The whole of pancreas, exocrine and and fibrocystic disease are preferable over mucoviscidosis endocrine, is embryologically derived from the foregut in view of the main pathologic change of fibrosis produced endoderm. The pancreas lies obliquely in the concavity of the duodenum as an elongated structure about 15 cm in the disease is transmitted as an autosomal recessive trait length and 100 gm in weight (see Fig. The head lying in the concavity of the duodenum and the uncinate process projecting from the head. The tail is the thin, tapering part of the gland towards multiple organs and systems such as pancreatic insufficiency, the hilum of the spleen. The exocrine pancreas constitutes 80 to 85% cirrhosis and respiratory complications. Depending upon the the exocrine part is divided into rhomboid lobules severity of involvement and the organs affected, the separated by thin fibrous tissue septa containing blood pathologic changes are variable. Fatty replacement of the pancreas and grossly granules in their cytoplasm, while the basal region is deeply visible cysts may be seen. The zymogen Microscopically, the lobular architecture of pancreatic granules are membrane-bound sacs which fuse with the parenchyma is maintained. There is increased interlobular plasma membrane and are then released into the lumina of the acini. The acini are atrophic and many of the acinar ductal branches into the small ducts in the lobules and ducts contain laminated, eosinophilic concretions. Atrophy of the exocrine pancreas may cause provides the main drainage for pancreatic secretions into the impaired fat absorption, steatorrhoea, intestinal duodenum. The bile canaliculi are plugged by viscid of the pancreatic and bile ducts in the ampulla of Vater, or mucous which may cause diffuse fatty change, portal less often both open separately into the duodenum. More severe involveOccasionally, the proximal part of the dorsal duct persists ment may cause biliary cirrhosis (page 625. The main functions of the exocrine pancreas are seen in almost all typical cases of cystic fibrosis.

Hypersecretion of sodium and chloride in the sweat observed in these patients may be reflected Cystic fibrosis of the pancreas or fibrocystic disease is a pathologically by diminished vacuolation of the cells of hereditary disorder characterised by viscid mucous eccrine glands. It is classified into acute and chronic forms both of Block in exocytosis of pancreatic enzymes occurring from nutritional causes results in activation of these intracellular which are distinct entities. Grossly, in the early stage, Acute pancreatitis is an acute inflammation of the pancreas the pancreas is swollen and oedematous. The severe form in a day or two, characteristic variegated appearance of of the disease associated with macroscopic haemorrhages grey-white pancreatic necrosis, chalky-white fat necrosis and fat necrosis in and around the pancreas is termed acute and blue-black haemorrhages are seen. The peritoneal cavity contains blood-stained ascitic fluid and condition occurs in adults between the age of 40 and 70 years white flecks of fat necrosis in the omentum, mesentery and is commoner in females than in males. The resolved lesions show areas the onset of acute pancreatitis is sudden, occurring after of fibrosis, calcification and ductal dilatation. The patient presents with Microscopically, the following features in varying grades abdominal pain, vomiting and collapse and the condition are noticeable: must be differentiated from other diseases producing acute abdomen such as acute appendicitis, perforated peptic ulcer, 1. Necrosis of the arteries and arterioles with areas of sudden occlusion of the mesenteric vessels. Inflammatory reaction, chiefly by polymorphs, around the latter being more specific for pancreatic disease. The two leading causes associated with acute survives may develop a variety of systemic and local pancreatitis are alcoholism and cholelithiasis, both of which complications. Less common causes of acute pancreatitis include trauma, ischaemia, shock, Systemic complications: extension of inflammation from the adjacent tissues, blood1. In a Local sequelae: proportion of cases of acute pancreatitis, the etiology remains 1. The destructive changes in the pancreas Mortality in acute pancreatitis is high (20-30%. Patients are attributed to the liberation and activation of pancreatic succumb to hypotensive shock, infection, acute renal failure, enzymes.

However blood pressure in spanish order altace from india, oral glucocorticosteroids are not invasive arteria communicans anterior purchase 10mg altace with amex, have relatively few adverse effects for a short course heart attack cough cheap altace 5 mg online, and are low cost heart attack 90 year old buy discount altace online. Evidence for the Use of Oral Glucocorticosteroids See Intracarpal Tunnel Glucocorticosteroid Injections ( Steroid Injections ) Section. Of the 6 articles considered for inclusion, 2 randomized trials and 4 systematic studies met the inclusion criteria. Recommendation: Routine Use of Opioids for Treatment of Non-Severe Acute Pain Routine opioid use is strongly not recommended for treatment of non-severe acute pain (e. Benefits Faster recovery, less debility, reduced accidents risks, risks of dependency or addiction. Strength of Evidence Strongly Not Recommended, Evidence (A) Level of Confidence High 2. Recommendation: Opioids for Treatment of Acute, Severe Pain Opioids are recommended for treatment of acute, severe pain (e. They also may be indicated at the initial visit for a brief course for anticipated pain accompanying severe injuries. Indications Patients should meet all of the following: 1) Severe injury with a clear rationale for use (objective functional limitations due to pain resulting from the medical problem,. Considerable caution is also warranted among those who are unemployed as the reported risks of death are also greater than 10-fold. Class I includes substances with a high potential for abuse and without a recognized medical use (e. There are considerable drug-drug interactions that have been reported (see Appendices 2-3 of Opioids Guideline. Frequency/Duration Generally, opioids should be prescribed at night or while not working. Recommend opioid use as required by pain, rather than in regularly scheduled dosing. If parenteral administration is required, ketorolac has demonstrated superior efficacy compared with opioids for acute severe pain,(684, 685) although ketorolacs risk profile may limit use for some patients. Parenteral opioid administration outside of obvious acute trauma or surgical emergency conditions is almost never required, and requests for such treatment are clinically viewed as red flags for potential substance abuse. Indications for Discontinuation Resolution of pain, sufficient improvement in pain, intolerance or adverse effects, non-compliance, surreptitious medication use, consumption of medications or substances advised to not take concomitantly (e. Harms Adverse effects are many (see section below on Opioids Benefits and Harms. Recommendation: Screening Patients Prior to Initiation of Opioids Initial screening of patients is recommended with more detailed screening for: i) requiring continuation of opioids beyond 2 weeks for those with an acute severe injury, and ii) at consideration of initiation for severe pain but no objective evidence. Screening should include history(ies) of depression, anxiety, personality disorder, other psychiatric disorder, substance abuse, sedating medication use (e. Those who screen positive, especially to multiple criteria, are recommended to: i) undergo greater scrutiny for appropriateness of opioids (may include psychological evaluation), ii) consideration of consultation and examination(s) for complicating conditions and/or appropriateness of opioids, and iii) if opioids are prescribed, more frequent assessments for compliance, achievement of functional gains,(655, 686, 687) adverse effects, and symptoms and signs of aberrancy. In cases where someone has elevated, but potentially acceptable risk, may alert the provider to improve surveillance for complications and aberrant behaviors. Strength of Evidence fi Recommended, Insufficient Evidence (I) Level of Confidence High 4. Recommendation: Opioid Dose Limits in Acute Pain Dispense only that which is required. The maximum daily oral dose recommended for opioidnaive, acute pain patients based on risk of overdose/death is 50mg morphine equivalent dose 84 Copyright 2016 Reed Group, Ltd. In rare cases with documented functional improvement (see Appendix 1 of Opioids Guideline), higher doses may be considered, however, risks are substantially higher and greater monitoring is also recommended (see Subacute/Chronic Opioid recommendations below. Lower doses should be used for patients at higher risk of dependency, addiction and other adverse effects. Monitoring is also recommended and consultation may be considered for those patients on higher doses. Harms Theoretical potential to undertreat pain in some patients with increased pain sensitivity. Benefits Reduced risk for adverse physical and cognitive effects, dependency, addiction and opioidrelated overdoses and deaths. Strength of Evidence Recommended, Evidence (C) Level of Confidence Moderate Figure 4. Morphine Equivalent Dosage (mg/d)* 12 10 Dunn (All Overdose Events) 8 Dunn (Serious 6 Overdose Events) 4 Bohnert (Chronic) 2 Bohnert (Acute) 0 Hazard Ratio=1. Recommendation: Limited Use of Opioids for Post-operative Pain Limited use of opioids is recommended for post-operative pain management as adjunctive therapy to more effective treatments. Evidence suggests perioperative pregabalin for 14 days and/or continuous femoral nerve catheter analgesia instead of solely using oral opioids results in superior knee arthroplasty functional outcomes with less venous thromboses. Due to greater than 10-fold elevated risks of adverse effects and death, considerable caution is warranted among those using other sedating medications and substances including: i) benzodiazepines, ii) anti-histamines (H1-blockers), and/or iii) illicit substances. Considerable caution is also warranted among those who are unemployed as the reported risks of death are also greater than 10-fold. There are considerable drug-drug interactions that have been reported (see Appendices 2-3 of Opioids Guideline. Inpatient management may moderate these recommendations provided there is careful monitoring, although these same management issues then apply post-discharge. Most patients should be making progress towards functional restoration, pain reduction and weaning off the opioids. Patients who have not progressed should be carefully evaluated for physical complications or psychiatric comorbidity, adherence to active treatments, and pending development of addiction or dependency. Frequency/Duration For moderate and major surgeries, opioids are generally needed on a scheduled basis in the immediate post-operative period. Other post-operative situations may be sufficiently managed with an as needed opioid prescription schedule. However, high dose use at night is not recommended due to respiratory depression and disruption of sleep architecture. Prescriptions of 90-day supplies in the post-operative setting are not recommended. Indications for Discontinuation the physician should discontinue the use of opioids based on sufficient recovery, expected resolution of pain, lack of efficacy, intolerance or adverse effects, non-compliance, surreptitious medication use, self-escalation of dose, or use beyond 3 to 5 days for minor procedures, and 2 to 3 weeks for moderate/less extensive procedures. Use for up to 3 months may occasionally be necessary during recovery from more extensive surgical procedures (e. However, with rare exceptions, only nocturnal use is recommended in months 2 to 3 plus institution of management as discussed in the subacute/chronic guidelines below. For those requiring opioid use beyond 1 month, the subacute/chronic opioid use recommendations below apply. Some studies suggest this may modestly improve functional outcomes in the post-operative population. Recommendation: Screening Patients Prior to Continuation of Opioids Screening of patients is recommended for patients requiring continuation of opioids beyond the second post-operative week. Screening should include history(ies) of: depression, anxiety, personality disorder, pain disorder, other psychiatric disorder, substance abuse history, sedating medication use (e. Those who screen positive, especially to multiple criteria, are recommended to: i) undergo greater scrutiny for appropriateness of opioids (e. Improved identification of more appropriate and safe candidates for opioids compared with attempting post-operative pain control with non-opioids. In cases where someone has elevated, but potentially acceptable risk, this may alert the provider to improve surveillance for complications and aberrant behaviors. Strength of Evidence fi Recommended, Insufficient Evidence (I) Level of Confidence High 3. Post-operative patients particularly require individualization due to factors such as the severity of the operative procedure, response to treatment(s) and variability in response. Lower doses should be used for patients at higher risk of dependency, addiction and other adverse effects. In rare cases with documented functional improvement, ongoing use of higher doses may be considered, however, risks are substantially higher and greater monitoring is also recommended (see Subacute/Chronic Opioid recommendations below. Harms Theoretical potential to undertreat pain, which could modestly delay functional recovery. Benefits Reduced risk for adverse effects, dependency, addiction and opioid-related deaths. Strength of Evidence Recommended, Insufficient Evidence (I) Level of Confidence Low viiiStatistical significance present for acute and chronic pain at and above 50 mg per day of morphine equivalent dose. Recommendation: Routine Use of Opioids for Subacute and Chronic Non-malignant Pain Opioid use is moderately not recommended for treatment of subacute and chronic nonmalignant pain. Opioid prescription should be patient specific and limited to cases in which other treatments are insufficient and criteria for opioid use are met (see below. Benefits Less debility, fewer adverse effects, reduced accident risks, lower risks of dependency, addiction, overdoses, and deaths. Strength of Evidence fi Moderately Not Recommended, Evidence (B) Level of Confidence High 2. Recommendation: Opioids for Treatment of Subacute or Chronic Severe Pain the use of an opioid trial is recommended if other evidence-based approaches for functional restorative pain therapy have been used with inadequate improvement in function. Indications Patients should meet all of the following: 1) Reduced function is attributable to the pain. Other medications to consider include topical agents, norepinephrine adrenergic reuptake blocking antidepressants or dual reuptake inhibitors; also antiepileptic medications particularly for neuropathic pain. However, if an opioid trial is contemplated, cessation of all depressant medications including muscle relaxants is advisable. If a trial is successful at improving function, prescriptions for up to 90-day supplies are recommended. Considerable caution is also warranted among those who are unemployed as the reported risks of death are also greater than 10-fold. There are considerable drug-drug interactions that have been reported (see Appendices 2-3 of Opioids Guideline. Frequency/Duration Opioids use is generally initiated as a trial to ascertain whether the selected opioid produces functional improvement (see Appendix 1 of Opioids Guideline. Opioid use is generally prescribed on a regular basis,(716) at night or when not at work. Lower opioid doses are preferable as they tend to have the better safety profiles, less risk of dose escalation,(681) less work loss,(682) and faster return to work. Theoretical potential to improve short-term function impaired by a painful condition. Strength of Evidence Recommended, Insufficient Evidence (I) Level of Confidence Low 3. Recommendation: Screening Patients Prior to Initiation of Opioids Screening of patients is recommended prior to consideration of initiating a trial of opioids for treatment of subacute or chronic pain. Screening should include history(ies) of depression, anxiety, personality disorder and personality profile,(683, 718, 719) other psychiatric disorder, substance abuse history, sedating medication use (e. Those who screen positive, especially to multiple criteria, are recommended to: i) undergo greater scrutiny for appropriateness of opioids (may include psychological and/or psychiatric evaluation(s) to help assure opioids are not being used instead of appropriate mental health care); ii) consideration of consultation and examination(s) for complicating conditions and/or appropriateness of opioids; and iii) if opioids are prescribed, more frequent assessments for compliance, achievement of functional gains and symptoms and signs of aberrant use. Improved identification of more appropriate and safe candidates for treatment with opioids. In cases where someone has elevated, but potentially acceptable risk, this may alert the provider to improve surveillance for complications and aberrant behaviors. Strength of Evidence fi Recommended, Insufficient Evidence (I) Level of Confidence High 4. Caution appears warranted in all patients as there is evidence the risk of dose escalation is present even among patients enrolled in a hold the line (stable dose) prescribing strategy treatment arm. For chronic pain patients, theoretical potential to undertreat pain and thus impair function. However, there is no quality literature currently available to support that position. Benefits Reduced risk for adverse effects, dependency, addiction, and opioid-related deaths. Recommendation: Use of an Opioid Treatment Agreement (Opioid Contract, Doctor/Patient Agreement, Informed Consent) the use of an opioid treatment agreement (opioid contract, doctor/patient agreement, or informed consent) is recommended to document patient understanding, acknowledgement of potential adverse effects, and agreement with the expectations of opioid use (see Appendix 1 of Opioids Guideline. Benefits Educates the patient and significant others that these medications are high risk, with numerous adverse effects. It provides a framework for initiation of a trial, monitoring, treatment goals, compliance requirement, treatment expectations, and conditions for opioid cessation. It should reduce risk of adverse events and opioid-related deaths, although that remains unproven to date. Strength of Evidence fi Recommended, Insufficient Evidence (I) Level of Confidence Moderate 90 Copyright 2016 Reed Group, Ltd. Recommendation: Urine Drug Screening Baseline and random urine drug screening, qualitative and quantitative, is recommended for patients prescribed opioids for the treatment of subacute or chronic pain to evaluate presence or absence of the drug, its metabolites, and other substance(s) use. Frequency Screening is recommended at baseline, randomly at least twice, and up to 4 times a year and at termination. Federal guidelines recommend at least 8 tests a year among those utilizing opioid treatment programs. Standard urine drug/toxicology screening processes should be followed (consult a qualified medical review officer. In the absence of a plausible explanation, those patients with aberrant test results should have the opioid discontinued or weaned.

However, decidual reaction the myometrium is the thick muscular wall of the uterus may be suggested in the absence of pregnancy due to which is covered internally by uterine mucosa called the extreme response to progesterone. The endometrium extends above the level of impossible to distinguish an advanced progestational the internal os where it joins the endocervical epithelium. In addition to the changes that take place during the normal the lesions pertaining to the corpus uteri and the menstrual cycle, the endometrium undergoes morphologic endometrium are numerous and constitute vast majority of changes when hormonal preparations are administered, or gynaecologic conditions. Oestrogen and Progesterone as it is generally called, is thin and atrophic with inactive glands and fibrous stroma. However, some of the glands Oestrogen produces the characteristic changes of may show cystic dilatation. Sometimes, retrogressive proliferative phase at the time of menopause and in young hyperplasia is seen which is characterised by Swiss-cheese women with anovulatory cycles as occurs in Stein-Leventhal pattern of glands resembling endometrial hyperplasia but syndrome. The therapeutic addition of progesterone composed of inactive retrogressive lining epithelium. There produces secretory pattern in an oestrogen-primed is intermingling of cystic and dilated glands with small and endometrium. Postmenopausal endometrium may show hormonal therapy is employed for control of conception. The endometrial glands are enlarged function is just beginning (menarche) or when it is waning with abundant glandular secretions and the stromal cells off (menopause. Anovulation is the result of prolonged and become more plump, polygonal with increased cytoplasm excessive oestrogenic stimulation without the development termed decidual reaction. The causes for anovulation at diffeextrauterine pregnancy show hyperactive secretory state rent ages are as follows: called Arias-Stella reaction. In pre-puberty: precocious puberty of hypothalamic, hyperchromatic, atypical, tall cells lining the glands and the pituitary or ovarian origin. In adolescence: anovulatory cycles at the onset of which may be mistaken for an adenocarcinoma. In reproductive age: complications of pregnancy, endoMenopause metrial hyperplasia, carcinoma, polyps, leiomyomas and the onset of menopause is heralded with hormonal adenomyosis. Most commonly, the senile endometrium, endometrial hyperplasia, carcinoma and polyps. It has been observed that women who ovulate may also occasionally have anovulatory cycles. In such cases, the premenstrual endometrial biopsy shows histologic lag of more than 2 days. Chronic form is more common and occurs by the same causes which result in acute phase. The endometrial glands are present endometritis is an example of specific chronic inflammation, deep inside the myometrium (arrow. In acute endometritis and logically benign endometrial tissue within the myometrium myometritis, there is progressive infiltration of the endoalongwith myometrial hypertrophy. The term adenomyoma metrium, myometrium and parametrium by polymorphs is used for actually circumscribed mass made up of and marked oedema. Adenomyosis is myometritis are characterised by infiltration of plasma cells found in 15-20% of all hysterectomies. The possible underlying endometritis is almost always associated with tuberculous cause of the invasiveness and increased proliferation of the salpingitis and shows small non-caseating granulomas endometrium into the myometrium appears to be either a (Fig. Clinically, the patients of adenomyosis generally complain of menorrhagia, colicky dysmenorrhoea and menstrual pain in the sacral or sacrococcygeal regions. On cut section, there is diffuse thickness of the uterine wall with presence of coarsely trabecular, ill-defined areas of haemorrhages. Microscopically, the diagnosis is based on the finding of normal, benign endometrial islands composed of glands as well as stroma deep within the muscular layer. The minimum distance between the endometrial islands within the myometrium and the basal endometrium should be one low-power microscopic field (2-3 mm) for making the diagnosis (Fig. The stroma has caseating Endometriosis and adenomyosis are closely interlinked, so epithelioid cell granulomas having Langhans giant cells and peripheral layer of lymphocytes. However, the two differ as regards age, fertility and involvement is often bilateral. Larger cysts, 3-5 cm in histogenesis and thus endometriosis should be regarded as diameter, filled with old dark brown blood form chocolate a distinct clinicopathologic entity. The chief locations where the abnormal endometrial Histologically, the diagnosis is simple and rests on identdevelopment may occur are as follows (in descending order ification of foci of endometrial glands and stroma, old or of frequency): ovaries, uterine ligaments, rectovaginal new haemorrhages, haemosiderin-laden macrophages septum, pelvic peritoneum, laparotomy scars, and and surrounding zone of inflammation and fibrosis infrequently in the umbilicus, vagina, vulva, appendix and (Fig. Transplantation or regurgitation theory is based on the proliferative patterns of glandular and stromal tissues and assumption that ectopic endometrial tissue is transplanted commonly associated with prolonged, profuse and irregular from the uterus to an abnormal location by way of fallopian uterine bleeding in a menopausal or postmenopausal tubes due to regurgitation of menstrual blood. Vascular or lymphatic dissemination explains the developoestrogenic stimulation unopposed with any progestational ment of endometrial tissue at extrapelvic sites by these routes. Such conditions include Stein-Leventhal syndrome, Endometriosis is characteristically a disease of functioning granulosa-theca cell tumours, adrenocortical reproductive years of life. Clinical signs and symptoms hyperfunction and prolonged administration of oestrogen. Grossly, the appearance the following classification of endometrial hyperplasias of endometriosis varies widely depending upon the is widely employed by most gynaecologic pathologists: location and extent of the disease. Simple hyperplasia without atypia (Cystic glandular endometriosis appear as blue or brownish-black hyperplasia. Complex hyperplasia without atypia (Complex nonfoci are surrounded by fibrous tissue resulting in atypical hyperplasia. The glands are increased in number, exhibit variation in size and are irregular in shape. The glands are lined by multiple layers of tall columnar epithelial cells with large nuclei which have not lost basal polarity and there is no significant atypia. Dense fibrocollagenic tissue contains endometrial glands, stroma and evidence of preceding old haemorrhage. The stroma is generally hyperplasia by the presence of atypical cells in the dense, cellular and compact (Fig. The cytologic features the malignant potential of complex hyperplasia in the present in these cells include loss of polarity, large size, absence of cytologic atypia is 3%. About 20-25% cases of untreated atypical atypia is distinguished from complex non-atypical hyperplasia progress to carcinoma. However, a few factors associated Tumours arising from endometrium and myometrium may with increased frequency of its development are chronic be benign or malignant. They may originate from different unopposed oestrogen excess, obesity, diabetes, hypertension tissues as under: and nulliparous state. There is irrefutable evidence of Endometrial glandsendometrial polyps, endometrial relationship of endometrial carcinoma with prolonged oestrogenic carcinoma. These evidences are as under: Endometrial stromastromal nodules, stromal sarcoma. Endometrial carcinoma has association with endometrial Smooth muscle of the myometriumleiomyoma, hyperplasia (discussed above) in which there is unopposed leiomyosarcoma. Patients receiving prolonged exogenous oestrogen Uterine polyp is clinical term used for a polypoid growth therapy are at higher risk of developing this cancer. Women of breast cancer receiving tamoxifen for prolonged leiomyomatous polyp and placental polyp), or malignant period have 2-fold increased risk of developing uterine polypoid tumours (e. Prolonged administration of oestrogen to laboratory is the one having the structure like that of endometrium and animals can produce endometrial hyperplasia and is termed endometrial or mucus polyp. Women with gonadal agenesis rarely develop endogenerally remain asymptomatic and are detected metrial carcinoma. The larger ones may ulcerate, degenerate and Pathogenetically, papillary serous variant of endometrial result in clinical bleeding. The role of heredity polyps may be single or multiple, usually sessile and small in pathogenesis of endometrial cancer is supported by higher (0. The histologic pattern (having simultaneous cancers of the breast, thyroid, and of the endometrial tissue in the polyp may resemble either endometrium. Grossly, endometrial Rarely, a large endometrial polyp may undergo malignant carcinoma may have 2 patternslocalised polypoid tumour, change. The tumour protrudes into the endometrial Endometrial Carcinoma cavity as irregular, friable and grey-tan mass. Extension Carcinoma of the endometrium, commonly called uterine of the growth into the myometrium may be identified by cancer, is the most common pelvic malignancy in females in the presence of soft, friable and granular tissue in cut the United States and Eastern Europe but is uncommon in section. In advanced disease, the involvement may extend Asia where cervical cancer continues to be the leading cancer beyond the physiologic limitsinto the cervical canal, into in women. Whereas the decline in the incidence of cervical the peritoneum, besides lymphatic metastases and cancer in the developed countries is due to aggressive cervical haematogenous metastases to distant sites such as lungs, screening programme leading to early detection and cure of liver, bones and other organs. It is primarily a adenocarcinomas due to their resemblance with normal disease of postmenopausal women, the peak incidence at endometrium. Depending upon the pattern of glands and onset being 6th to 7th decades of life and is uncommon below individual cell changes, these may be well-differentiated, the age of 40 years. The most important presenting complaint moderately-differentiated or poorly-differentiated. A, B, Diagrammatic representation of the common gross patternslocalised polypoid growth and diffuse growth. C, the specimen of the uterus and cervix shows enlarged uterus and dilated uterine cavity containing irregular, grey-white, friable growth arising from endometrial mucosa and invading the underlying myometrium superficially. The glandular epithelium G2: Moderately-differentiated (glandular and partly solid shows stratification, formation of tufting and papillae and areas. Most growths are well-differentiated G3: Poorly-differentiated (predominantly solid. Moderately-differentiated adenocarcinoma shows all the Papillary serous carcinoma of the endometrium resembling above features alongwith presence of some solid sheets its ovarian counterpart is distinct since it occurs in the of malignant cells. Uncommon histologic variants of endometrial carcipresence of solid sheets and ribbons of malignant epithenoma are: adenocarcinoma with squamous metaplasia lial cells which show marked cytologic atypia and frequent (adenoacanthoma), adenosquamous carcinoma (when both mitoses. The most common histologic pattern is well-differentiated adenocarcinoma showing closely packed (back-to-back) glands with cytologic atypia. Histologically, they are essentially composed of 2 tissue elementswhorled bundles of smooth muscle cells Leiomyoma admixed with variable amount of connective tissue. The smooth muscle cells are uniform in size and shape with Leiomyomas or fibromyomas, commonly called fibroids by abundant cytoplasm and central oval nuclei (Fig. About 20% of women above sarcoma but is distinguished from it by the absence of the age of 30 years harbour uterine myomas of varying size. The pathologic appearance may be altered by Malignant transformation occurs in less than 0. Symptomatic cases may produce abnormal hyaline degeneration, cystic degeneration, infarction, uterine bleeding, pain, symptoms due to compression of calcification, infection and suppuration, necrosis, fatty surrounding structures and infertility. The cause of leiomyomas is unknown but the possible stimulus to their proliferation is oestrogen. Other possible factors implicated compared to its rather common benign counterpart. A, Diagrammatic appearance of common locations and characteristic whorled appearance on cut section. B, Sectioned surface of the uterus shows multiple circumscribed, firm nodular masses of variable sizessubmucosal (white arrows) and intramural (black arrows) in location having characteristic whorling. C, the opened up uterine cavity shows an intrauterine gestation sac with placenta (white arrow) and a single circumscribed, enlarged, firm nodular mass in intramural location (black arrow) having grey-white whorled pattern. Microscopy shows whorls of smooth muscle cells which are spindle-shaped, having abundant cytoplasm and oval nuclei. The peak age incidence types of cells namely: ciliated, columnar and dark intercalated is seen in 4th to 6th decades of life. The tubal serosal covering may contain tiny nodular are nonspecific such as uterine enlargement and abnormal masses of mesothelial cells forming Walthards cell rests. The major conditions involving the fallopian tubes are inflammations, ectopic tubal gestation, and endometriosis. Grossly, the tumour may form a diffuse, bulky, soft and fleshy mass, or a polypoid mass projecting into lumen. Leiomyosarcoma is liable to recur after removal and In addition, haematogenous spread may occur, though this eventually metastasises to distant sites such as lungs, liver, route is more important in the pathogenesis of tuberculosis. Patients generally complain of lower abdominal and the fallopian tube or oviducts are paired structures, each pelvic pain which is often bilateral, dysmenorrhoea, extending from superior angle of the uterus laterally to the menstrual abnormalities and fever with tachycardia. The distal end infundibulum is fringed by fimbriae, the longest of which is blocked by inflammatory exudate and the lumina are called fimbria ovarica is attached to the ovary. There may be formation of loculated tubo-ovarian Histologically, the wall of tube has 4 coatsserous abscess involving the tube, ovary, broad ligament and forming the peritoneal covering, subserous consisting of adjacent part of uterus. The process begins with acute salpingitis characterised by oedema and intense acute inflammatory infiltrate of neutrophils involving the tubal mucosa as well as wall. The lumen is filled with purulent exudate consisting of leucocytes and sloughed off epithelial cells. The purulent process may extend to involve tube as well as ovary causing salpingo-oophoritis and forming tubo-ovarian abscess. The escape of purulent exudate into the peritoneal cavity produces pelvic peritonitis and pelvic abscess.
