Back to back closely packed gland like structures lined by pleomorphic malignant epithelial cells with hyperchromatic nuclei and eosinophilic cytoplasm. Laurens classification of gastric carcinoma include diffuse signet ring cells and intestinal types. Nuclear Grooves are seen. Keratin pearls — Squamous cell carcinoma. Views View Edit History. Few Characteristics Exclusive to Lesions — Rapid revision: Papillary structures with fibrovascular cores lined by pleomorphic malignant epithelial cells with Orphan Annie nuclei.

Ejqz Sarcoma PNET of bone consists of malignant round to oval tumor cells with cytoplasm containing glycogen. Eosinophilic secretions are noted. Osteoid formation — Osteosarcoma. Seminomatous germ cell tumors are radiosensitive and chemo responsive while non seminomatous tumors are vice versa.
Heterogenous population of cells including wagis cells,macrophages and eosinophils Characteristic feature. Antoni A cellular areas and Antoni B myxoid areas are seen in Schwanommas. Aschoff bodies ,pathognominic of Rheumatic fever,are foci ejazz swollen eosinophilic collagen surrounded by lymphocytes ,occasional plasma cells and plump macrophages called Anitschkow cells. Hyaline arteriosclerosis is benign hypertensive vascular change showing thickening and hyalinization of the walls with narrowed lumina of small vessels.
These components are arranged in central core and fibrous cap. Calretenin is the immunomarker for mesothelioma. Nodules composed of benign hepatocytes separated by thin fibrous tissue septae. Verocay bodies Antoni A and B — Schwanomma. Chicken wire calcification is seen in chondroblastoma. Gleason Score is done for the grading of Prostatic adenocarcinomas. 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.
DHT is the source of hyperplasia.

Multiple Myeloma is characterized by bence jones proteinuria,cast nephropathy,hypercalcemia,hyperuricemia and light chain deposition disease.
Sheets of malignant oval to polygonal cells with hyperchromatic nuclei and prominent pink nucleoli. LCA is the universal leukocyte marker.
Cytokeratin is the immunomarker for epithelial tumors and Vimentin is the marker for mesenchymal tumors. Desmin — Muscle marker. From Wikimedia Commons, the free media repository. It is locally aggressive tumor,which rarely metastasize.

Desmin is positive in skeletal muscle tumors. CD3,4,5 ,8 — T cell Lymphoma Marker. Adenoid cystic carcinoma is a common malignant salivary gland tumor.
It comprises of A for activity and F for fibrosis.
Schiller Duval bodies — Yolk sac tumor. Methenamine silver and PAS stains are done for kidney biopsies to see thickening of basement membrane of capillaries. In Myocardial infarction,coagulation necrosis starts in 4 to 12 hrs and collagen deposition starts in 10 to 14 days. Medullary Carcinoma is linked with amyloid wris. Small cell carcinoma of the lung shows maximum paraneoplastic syndromes — most common cushing like picture and ADH like morphology. Key processes in atherosclerosis are intimal thickening and lipid accumulation.
