Abstract:
We report a case of renal oncocytoma in 46-year old woman and review the literature. She had been asymptomatic except a visible protruding mass on the left abdomen and she underwent successful transperitoneal nephrectomy. The kidney weighed 4,800 gm, presented a well capsulated round mass and homogenous tan-brown colored cut surface. Renal oncocytoma, a rare neoplasm thought to arise from proximal tubular epithelial cells, exhibits a benign clinical course. They tend to misdiagnosed as renal cell carcinoma preoperatively. Histopathological studies confirm the oncocytic feature of the tumor cells, it shows finely granular eosinophilic cytoplasm(oncocyte) light microscopically, and the cytoplasm is filled with innumerable mitochondria with a paucity of other organelles ultrastructurally.
