Ductal structures,sheets and groups of pleomorphic malignant epithelial cells with hyperchromatic nuclei and eosinophilic cytoplasm. Endometrial carcinoma arises on two backgrounds: Peripheral palisading is seen in nests of tumor cells in Basal cell carcinoma Rodent ulcer. Dysgerminoma is the counterpart of seminoma in females. Crescents are seen in rapidly progressive glomerulonephritis,diffuse thickening of the glomerular capillary wall with silver spikes are seen in membranous glomerulonephritis and focal thickening of glomerular basement membrane with silver tram track appearance is seen in membranoproliferative glomerulonephritis.

Syncitial,transitional,fibroblastic,psamommatous and secretory types fall into type 1,Clear cell and chordoid types of meningiomas fall into atypical variety and Papillary and Rhabdoid types fall into malignant variety. Panacinar emphysema is linked with alpha 1 antitrypsin deficiency. PT1 is for lamina propria and PT2 is for muscle wall invasion in Transitional cell tumors. ANCA are antineutrophil cytoplasmic antibodies seen in patients with vasculitis. Gleason Score is done for the grading of Prostatic adenocarcinomas.
MEN -2A or Sipple syndrome shows pheochromocytoma,medullary carcinoma thyroid and parathyroid hyperplasia. Sheets of malignant oval to spindly cells with hyperchromatic nuclei. It is the most radiosensitive. From Wikimedia Commons, the free media repository. PTEN is the antioncogene altered in endometrial hyperplasia and adenocarcinoma. Squmaous cell carcinoma is characterized by sheets and groups of pleomorphic malignant squamous epithelial cells with hyperchromatic nuclei and pale cytoplasm.
TNM Staging of Lung. Key processes in atherosclerosis are intimal thickening and lipid accumulation. Views View Edit History. Myxoma is the most common primart tumor of heart in adults and Rhabdomyoma is most commonest in children.
WHO grading of Astrocytoma include: Renal cell carcinoma is of 4 major types: This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.
Multiple Myeloma is characterized by bence jones proteinuria,cast wqris and light chain deposition disease. Synovial Sarcoma shows dual line of differentiation both epithelial like and spindly mesenchymal cells are seen.
Rosenthal fibers,eosinophilic granular bodies and microcysts are seen in low grade Pilocytic astrocytoma. Immunomarker is CD 15 and CD The cells are monomorphic with abundant granular cytoplasm.
Piecemeal necrosis — Chronic active hepatitis. The lesion is caused by KSHV and shows three morphological stages: Choriocarcinoma shows no chorionic villi.

Seminomatous germ cell tumors are radiosensitive and chemo responsive while non seminomatous tumors are vice versa. Benign prostatic hyperplasia includes two components: Nodules composed of benign hepatocytes separated by thin fibrous tissue septae.
Nodular melanoma has two pattern of growths,horizontal and vertical. Psamomma bodies — Papillary carcinoma thyroid,Papillary serous ovarian tumors,Meningioma.
Small cell carcinoma eejaz the lung shows maximum paraneoplastic syndromes — most common cushing like picture and ADH like morphology.

Vasculitis are divided into three types: Chronic cholecystitis is the inflammation of gall bladder revealing subepithelial fibrosis and chronic inflammation in the lamina propria. Epithelioid and sarcomatoid types are noted in a mesothelioma. Glandular wall sharing is one of the hall mark sign of adenocarcinomas.
