There is a biliary pattern of cirrhosis with large irregular jigsaw-like nodules of hepatocytes. If the biopsy is taken from an area unaffected by the primary disease, but distal to a large duct stricture, the liver shows features of duct obstruction i. Large vessels are often present within the lesion, but portal tracts are absent.

Most lesions have a characteristic central scar. Large thick-walled vessels are very often present and a helpful diagnostic clue. Inspissated bile may be present within the ductules. Bile is not present in the ductules.

Bile production may be seen by the tumour. As this duct drains into the duodenum via the smaller minor papilla, there is a tendency to stasis of pancreatic secretions and susceptibility to pancreatitis. The endocrine tissue is typically spared until late in the disease. Large ducts are dilated and contain inspissated secretions. Patients often have raised serum IgG4 levels.

This variant is thought to be autoimmune in nature.

Treatment is supportive only and most patients will have other alcohol-related pathology. Tumours may be functioning or non-functioning, depending on whether a syndrome of inappropriate hormone secretion is present. Uncertain behaviour: The epithelial cells may show a range of atypia from low to high grade. Invasive carcinoma can arise within this lesion.

The cysts do not communicate with the pancreatic ductal system. The epithelial component may show a range of atypia from low to high grade. Invasive carcinomas can arise within these lesions. Histologically, the small cysts are lined by cuboidal cells with a round nucleus and clear cytoplasm due to the accumulation of glycogen. The cells tend to be poorly cohesive and fall apart, creating pseudopapillary and cystic areas.

Nevertheless, these features on a renal biopsy support a diagnosis of hypertensive nephropathy provided the clinical picture is compatible. Biopsy is usually reserved for atypical cases where an alternative diagnosis may be possible. Careful exclusion of other known causes of segmental glomerulosclerosis is, therefore, essential before making a diagnosis of FSGS as this labels the patient with a disease expected to rapidly progress to end-stage renal failure.

In these cases, the immune complexes probably form elsewhere and circulate to the kidneys where they are deposited within the glomeruli. The peak incidence is in adults from 20—40y. Distinction between the two is usually possible, based on the clinical picture and the pattern of scarring. Distinction is usually possible, based on the clinical picture and pattern of scarring. The presence of fetal cartilage is a characteristic feature. The precise clinical picture will depend on whether the obstruction is acute or chronic, involves the upper or lower urinary tract, and whether it is unilateral or bilateral.

Most patients have absorptive hypercalciuria in which too much calcium is absorbed from the gut. Others have renal hypercalciuria in which calcium absorption from the proximal tubule is impaired. Only a minority have hypercalciuria due to hypercalcaemia which is usually due to primary hyperparathyroidism. The ammonia alkalinizes the urine and promotes precipitation of magnesium ammonium phosphate salts. However, most patients do not have hyperuricaemia nor increased urinary excretion of uric acid.

It is thought that these patients have a tendency to make slightly acidic urine which is prone to forming uric acid stones. They may be asymptomatic or picked up following investigation of haematuria or recurrent UTIs.

Common points of impaction are the pelviureteric junction, the pelvic brim, and the vesicoureteric junction. Complications 2 Complete obstruction of the urinary tract requires urgent intervention to remove the stone. Large tumours are nevertheless often excised. These are more likely to be multiple and bilateral.

Entrapped tubules may be found at the edge of the lesion. The vasculature within the tumour is thick-walled. Grade 1 has the best prognosis and grade 4 the worst. Extensive vascular invasion is usually evident. This group is not formally subdivided into low and high grade, though most show high-grade nuclear atypia. The presence of lymphovascular invasion is an adverse prognostic factor. Regional lymph nodes N pN1: Common basal cell markers used for this purpose include p63 and high molecular weight keratins.

In practice, patterns 1 and 2 are virtually never diagnosed and so almost all prostate cancers have a Gleason score between 6 and A higher score is associated with poorer tumour differentiation and worse outcome. The tumours may grow in solid sheets or form glandular structures. There is often extensive haemorrhage and necrosis.

Patients tend to present with a more purulent discharge and dysuria. Seen mostly in sexually active young men.

Circumcision is associated with a reduction in risk. Neutrophils are present within the parakeratosis. Erosive disease may occur, which can lead to scarring. The overlying epidermis shows basal cell damage and may be thickened or atrophic. There may be areas of atrophy and haemorrhage. Itching, burning, and dyspareunia are common symptoms.

The epithelium covering the papillae is double-layered, with inner tall columnar cells and outer small myoepithelial cells. Stage IB: Stage II: Stage III: Stage IV: A thick white discharge is common.

Dyspareunia and dysuria may also occur. Stellate and multinucleate stromal cells are typically seen within the core near the epithelial surface.

Tumour may be seen projecting through the vaginal opening. Some tumour cells have brightly eosinophilic cytoplasm; cytoplasmic cross-striations may be visible. The lower incidence is largely attributable to the success of cervical screening programmes. Loss of function of these proteins results in uncontrolled proliferation of the infected cells. Residual CIN may be seen adjacent to small tumours. Residual CGIN may be seen adjacent to small tumours.

Women with two tests reported as mild dyskaryosis must then be referred for colposcopy. Almost all cases occur within the pelvis, most commonly the ovaries, uterosacral ligaments, pelvic peritoneum, pouch of Douglas, and sigmoid colon. Endometriosis is also recognized at sites outside of the pelvis such as surgical scars and the lungs, but this is rarer. Credence to this theory is lent by experimental induction of endometriosis in animals by placing endometrial tissue in the peritoneal cavity.

Given that the peritoneum and female genital tract arise from the same embryological cells coelomic epithelium , this seems plausible and would account for endometriotic deposits in areas in which implantation is unlikely. This would account for cases arising in locations where implantation and metaplasia are improbable such as the lung.

There is little evidence to support tubal distortion as a cause in most women. There is often abundant surrounding haemorrhage. Loss of function of PTEN is typical. Loss of function of TP53 gene is typical. Both are high-grade malignancies with extensive spread at presentation. These include cellular leiomyoma, highly cellular leiomyoma, mitotically active leiomyoma, and atypical leiomyoma. Although uncommon, it represents the most com- mon uterine sarcoma.

Histologically, leiomyosarcomas are smooth muscle tumours which demonstrate a number of atypical features such as diffuse cytological atypia, tumour cell necrosis, and high mitotic activity. Leiomyosarcomas are aggressive malignancies with a tendency to local recurrence and metastasis, particularly to the liver and lungs. Nuclear grooves may be seen. Some cysts may also contain luteinized cells.

Nuclear grooves are not present. The lining is composed of fully luteinized granulosa and theca cells. They are predominantly of clinical importance as large cysts may raise concern for a cystic neoplasm.

The most serious complication is torsion or rupture, leading to an acute abdomen. Hair, cartilage, bone, and teeth may be visible. They are often small and discovered incidentally. Large tumour may cause abdominal pain and ascites. The vast majority of borderline epithelial tumours are serous in type borderline serous tumours.

Macroscopically, they are large, usually mul- tilocular, cystic tumours that are frequently bilateral. The cysts often show many papillary excrescences growing from the surface.

Histologically, the tumours are composed of complex branching papillae covered by prolif- erating columnar epithelial cells demonstrating low-grade nuclear atypia. Histologically, these implants are divided into non-invasive and invasive types. Most are of the non-invasive type and these patients tend to have a favourable prognosis.

Invasive implants are generally associated with an adverse prognosis, but are much rarer. Some workers speculate that these tumours arise from paraovarian Mullerian epithelium through a sequence of benign cystadenoma l borderline neoplasm l invasive carcinoma. Some workers speculate that these tumours may, in fact, arise in other pelvic organs e.

Psammoma bodies may be present. Areas of squamous differentiation are common. Both organisms are sexually transmitted bacteria.

Nearly all occur in the Fallopian tubes, usually in the ampullary region. Other sites include the ovaries and abdominal cavity, but these are rare. Two types are recognized: They arise from fertilization of an anucleate ovum by a haploid sperm which then duplicates its genetic material. They arise from fertilization of an ovum by two sperms. Usually, there is no clinical suspicion of molar pregnancy, the diagnosis being made following histopathological examination of the evacuated products of conception.

The villi have a myxoid stroma containing collapsed empty blood vessels and karyorrhectic debris. There is abnormal non- polar trophoblastic hyperplasia and sheets of pleomorphic extravillous trophoblast may be present.

A prominent implantation site reaction is often seen, but with the absence of the normal trophoblast plugging of decidual blood vessels. Abnormal non-polar trophoblastic hyperplasia is present, though this is usually focal and less marked than in complete moles. The implantation site is usually unremarkable with normal trophoblast plugging of decidual blood vessels.

About half develop from a preceding hydatidiform mole with the remainder following a nor- mal pregnancy or non-molar miscarriage. Histologically, choriocarcinomas are composed of a mixture of cytotrophoblast and syncytiotrophoblast, typically forming bilaminar structures. Choriocarcinomas have a great propensity for vascular invasion, leading to early dissemination to multiple distant sites. Fortunately, gestational choriocarcinomas respond extremely well to chemotherapy and the prognosis for most women is very good.

Villous blood vessels are often small and inconspicuous. Maternal decidual arteries show failure of physiological conversion by trophoblast. Fibrin microthrombi may be seen within glomerular capillary loops in more severe cases. Prognosis 2 Delivery is the only cure for pre-eclampsia. The danger to the fetus from premature delivery must be weighed against the risks to the mother. The disease behaves very unpredictably and can progress very rapidly so patients must be closely monitored for signs of deterioration.

The discharge may be clear, creamy, or bloodstained. The terminal duct lobular unit is compressed into slit-like channels. The stroma shows variation in cellularity and composition of the extracellular matrix.

All phyllodes tumours have the potential for local recurrence and are usually treated by wide local excision. In practice, most do not recur, even following simple enucleation. Phyllodes tumours can develop the capacity to metastasize, but this is very rare. Papillomas can develop anywhere in the ductal system, but show a predilection for either small terminal ductules peripheral papillomas or the large lactiferous ducts central papillomas.

This is thought to be the earliest morphological precursor to low-grade ductal carcinoma in situ. The relative risk is quoted as between 7—12 times that expected in women without lobular neoplasia. Necrosis in the centre of the duct is unusual. Central necrosis may be present. Central necrosis is common. Prognosis depends on the persistence of any neoplastic cells after treatment. Recurrence is more likely with extensive disease, high nuclear grade, and the presence of comedo necrosis.

Genetically, they have simple diploid or near diploid karyotypes and as a hallmark, show deletion of 16q and gains of 1q. Genetically, they have complex karyotypes with many unbalanced chromosomal aberrations. Frequent changes include loss of 1p, 8p, and 17p and gains of 1q and 8q. Background bare bipolar nuclei are absent. They often occur in young women and are linked to BRCA mutations. Immunohistochemically, they are characterized by the expression of basal-type keratins, e.

These tumours appear to have a propensity to visceral metastasis, notably to the lungs and brain. This usually implies the biopsy missed the area of interest. This category mainly consists of lesions which may be benign in the core, but are known to show heterogeneity or to have an increased risk albeit low of an adjacent malignancy. The periductal stromal is often cellular and oedematous. Autoantibodies against beta cells and insulin may also be relevant. Lack of insulin causes the breakdown of protein in muscle and of triglyceride in fat, providing substrates for gluconeogenesis in the liver.

This, together with glucose formed from glycogen in the liver, causes hyperglycaemia. Cataract Retinopathy Ischaemic heart disease Diabetic nephropathy Acute pyelonephritis Peripheral vascular disease Peripheral neuropathy Fig.

This is fortu- nate as the highly cellular aspirates can easily be mistaken for a neoplastic process by the unwary. This can only be done histologically.

Four major types are recognized: Thyroid function is usually normal. Anaplastic carcinoma usually presents with a rapidly enlarging neck mass; involvement of nearby structures causes hoarseness, dysphagia, and dyspnoea. They are often multifocal.

Multinucleated giant cells, psammoma bodies, and thick colloid may be present. Some cells may have eccentric nuclei, imparting a plasmacytoid appearance. The nuclei contain coarsely granular chromatin. Fragments of amyloid may be seen. Although most tumours have a papillary architecture, this is not a prerequisite for the diagnosis.

Follicular carcinomas are subdivided into two major types: Amyloid deposits may be seen. Extensive necrosis is seen and occlusion of vessels by tumour is common. Widely invasive follicular carcinomas and medullary carcinomas are intermediate-grade malignancies with a higher risk of metastasis and mortality. Anaplastic carcinomas are highly malignant and almost always fatal within months of diagnosis.

A compressed rim of normal parathyroid tissue is often present at one edge. The cells may be arranged in solid sheets, trabeculae, or follicles. Follicle formation is unusual. This involves an intramuscular injection of synthetic adrenocorticotropic hormone ACTH. The normal response is a rise in plasma cortisol. Nuclei are round to oval and usually bland. The mean size is 12cm. Most arise in the adrenal medulla or paraspinal sympathetic ganglia.

Staging system for neuroblastomas Stage 1: Stage 2A: Stage 2B: Stage 3: Stage 4: Stage 4S: MEN 1. IL-6 lead to reduced sensitivity of the marrow to erythropoietin and failure to incorporate iron into developing red cells.

Megaloblastic anaemia due to autoimmune gastritis is also known as pernicious anaemia. This affects about 1 in people with a female predilection. The main dietary sources of folate are leafy green vegetables.

The latter is potentially fatal. There may be a very mild microcytic anaemia. Patients are usually asymptomatic and have normal Hb levels. They are nevertheless genetically important as carriers of the sickle cell gene. Their red cells sickle in venous blood, causing persistent haemolysis and episodes of vascular crises.

HbS readily precipitates and the solution goes cloudy. The leukocyte count may be decreased, normal, or increased. There may be leukocytosis. Susan Ashbrook Harvey. Ian Greaves.
