Morphologic heterogeneity and markers of renal cell

Acquired cystic disease associated renal cell carcinoma Most common kidney tumor in patients with end stage renal disease and acquired cystic disease Characterized by abundant calcium oxalate crystals and variable morphology: papillary, solid, eosinophilic and clear cell-like areas Tubulocystic renal cell carcinoma Although common RCC and papillary RCC both are derived from the same part of the renal tubule and have a similar antigenic phenotype, they differ in genetic changes. This might be explained by the fact that common RCC arises from mature renal tubular cells, whereas papillary tumors are from embryonal origin

1. BACKGROUND Renal cell carcinoma (RCC) accounts for about 2% of all cancers, with an worldwide annual increase of 1.5-5.9% (1,2). The mean age at the time of diagnosis is about 70 years and there is a predominance of men ove Grading of renal cell carcinoma (RCC) has been recognised as a prognostic factor for almost 100 years. Numerous grading systems have been proposed, initially focusing upon a constellation of cytological features and more recently on nuclear morphology. It has been recommended that grading of RCC should be based upon nucleolar prominence. Morphology •Renal cell carcinomas may arise in any portion of the kidney, but more commonly affects the poles. 11. RCC Morphology • One of the striking characteristics of renal cell carcinoma is its tendency to invade the renal vein and grow as a solid column of cells within this vessel. 12.

Renal cell carcinoma, disease arising from malignant epithelial cells in the kidneys. Renal cell carcinoma is responsible for about 90 percent of kidney cancers in adults and appears to arise from both genetic and environmental factors. Learn about the causes, symptoms, and treatment of renal cell carcinoma Renal Cell Carcinoma (RCC) metastasizes in approximately 20-30% cases. The most common sites for metastases are the lungs, bones, liver, and brain. Metastases of RCC in the gastrointestinal tract (GIT) are very rare. Metastatic RCC has a poor prognosis. We herein present a case series of three patients with metastatic disease in the colon, duodenum, and pancreas following complete resection. Renal cell carcinoma (RCC) accounts for 3% of malignant tumors and is the seventh leading cause of cancer deaths in the USA. An estimated 63,000 new renal tumors were diagnosed in 2013 with over.

Chromophobe renal cell carcinoma is a malignant distinct subtype of renal cell carcinoma and comprises approximately 5% of neoplasms of the renal tubular epithelium, originating in the distal nephron. It has been described as having a compact growth pattern of large tumor cells, having a translucent and reticular cytoplasm and distinct cell. A carcinoma arising from the renal parenchyma. The incidence of renal cell carcinoma has increased by 35% from 1973 to 1991. There is a strong correlation between cigarette smoking and the development of renal cell carcinoma. The clinical presentation includes : hematuria, flank pain and a palpable lumbar mass Background:The distinction between renal cell carcinoma conventional (clear cell) type with eosinophilic morphology (ccRCC), chromophobe renal cell carcinoma eosinophilic variant (chRCC), and renal oncocytoma (RO) is a common diagnostic dilemma. We aimed to identify an immunohistochemical panel to discriminate ccRCC from its morphologic mimics. Materials and Methods:Fifty-three renal neoplasms.

Cell lines are still a tool of choice for many fields of biomedical research, including oncology. Although cancer is a very complex disease, many discoveries have been made using monocultures of established cell lines. Therefore, the proper use of in vitro models is crucial to enhance our understanding of cancer. Therapeutics against renal cell cancer (RCC) are also screened with the use of. Pathologists must distinguish clear cell renal cell carcinoma (RCC), papillary RCC, chromophobe RCC, and the other morphologic entities to preserve the quality of studies and to guide the election of new treatments. Strict morphologic and immunohistologic criteria for cellular identification must be followed, and they must be prepared for future molecular substratification of histologic subtypes carcinoma,(1-7, 13-17) although there are likely examples of clear cell renal cell carcinoma with chromosome 3p loss or VHL alterations that mimic this morphology for various reasons.(2, 7) The category of such renal cell tumors with prominent stroma has bee Renal cell carcinoma is a male-predominant (2:1 ratio) disease with a typical presentation in the sixth and seventh decades of life (median age about 60 years).

ALK-rearranged renal cell carcinoma is a distinct type of renal cell carcinoma included in the so-called emerging/provisional RCC. The 2013 International Society of Urological Pathology (ISUP) Vancouver Classification of (adult) renal neoplasia identified a category of emerging or provisional new entities Results: Compared with 2D culture, the 3D organoid cultures retained the characteristic lipid-rich, clear cell morphology of clear cell renal cell carcinoma. Carbonic anhydrase 9 and vimentin were validated as biomarkers of renal cell carcinoma. Expression of the two validated biomarkers was more enhanced in 3D organoid culture Anti-renal cell carcinoma (RCC) recognizes a 200 kD glycoprotein localized in the brush border of the proximal renal tubule. This antibody immunoreacts with approximately 90% of primary renal cell carcinomas and approximately 85% of metastatic renal cell carcinomas. Other tumors that may react with this antibody are parathyroid adenoma and an. The tumour morphology demonstrated a predominance of low-grade clear cell renal carcinoma; however, the presence of scattered areas with syncytial-type giant cells raised the grade to 3/3 according to the WHO grading system .
