Hypercalcemia is shown by squamous cell carcinoma of lung. WHO grades Transitional cell tumors into Urothelial papilloma,urothelial neoplasm of low malignant potential,low grade papillary urothelial carcinoma and high grade papillary urothelial carcinoma. Chronic pyelonephritis is characterized on gross examination by a corticomedullary scar and on microscopy by tubular atrophy and dilation,thyroidization and chronic interstitial inflammation. Some other Last Points in Special Pathology not to be missed: Epithelioid and sarcomatoid types are noted in a mesothelioma.

Immature or malignant teratomas show sheets of undifferentiated cells,not seen in a benign teratoma. WHO grading of Astrocytoma include: ANCA are antineutrophil cytoplasmic antibodies seen in patients with vasculitis.
Mitoses can be seen. Carcinoma breast,fibrocystic disease,fibroadenoma,non specific abscess. Tubular carcinoma of breast carries wairs best prognosis. The thought of origin is post germinal center B-Cell. Aggregates of closely arranged thin walled vascular channels lined by benign endothelium and separated by scanty fibrous stroma. ER — PR postivie breast carcinomas carry better prognosis and are responsive to antiestrogen drugs.
Pheochromocytoma is composed of polygonal to spindle shaped chromaffin cells clustered with the sustentecular cells into small nests of alveoli Zell ballen appearance by a rich vascular network. Papillary carcinoma is the commonest thyroid malignancy,linked with history of childhood radiation.
Asbestos is linked with Mesothelioma and Bronchogenic Carcinoma.
Diagnosis rests on nuclear features ,the nuclei typically are optically clear empty -Orphan Annie appearance,show intranuclear inclusions warks intranuclear grooves.
Whorls like arrangement — Meningioma.

The thalassemia syndromes are a heterogenous group of inherited disorders caused by genetic lesions leading to decreased synthesis of either the alpha or beta globin chain of HbA. FNAC deep lumps common sites include — Liver,lung and abdominal lymph nodes. Atherosclerotic plaque consists of 3 components: Sheets and groups of seminoma cells with hyperchromatic vesicular nuclei and water clear cytoplasm.
When give Differential diagnosis of any lump always go in this order: Epithelioid and sarcomatoid types are noted in a mesothelioma. Diabetic glomerulosclerosis is characterized by capillary eja membrane thickening,diffuse mesangial sclerosis ,kimmelstiel-wilson nodules PAS positive ,capsular drops and fibrin caps Syncitial,transitional,fibroblastic,psamommatous and secretory wariz fall into type 1,Clear cell and chordoid types of meningiomas fall into atypical wxris and Papillary and Rhabdoid types fall into malignant variety.
Reactive eja node enlargement ,Tuberculous lymph node,LymphomaMetastatic malignancy. Endometrial carcinoma arises on two backgrounds: Cystic lesion lined by benign stratified squamous epithelium and cyst wall showing hair follicles,sebaceous glands. Medullary Carcinoma is linked with amyloid deposition. Psamomma bodies may also be seen.
