Abstract
Renal oncocytoma was first described by Zippelin 1942 as a malignant entity, however, Klein and valensi were able to demonstrate its benign characters in the year 1976. The current the World Health Organization have classified renaloncocytomas as benign renal neoplasms in 2004. Renal oncocytoma is the second most common benign renal neoplasm after angiomyolipoma, comprising 3-7% of all renal tumors, usually occur during the seventh decade of life varying from 20 to 86 years of age with males predominance. Zhou defined renal oncocytoma as a benign epithelial neoplasm composed of round-to polygonal-cells with abundant mitochondriarich eosinophilic cytoplasm, thought to arise from the intercalated cells in the kidney. The size of the tumors varies from 0.6 to 14 cm(7). Unfortunately, most oncocytomas are very difficult to be differentiated from renal cell carcinoma both clinically and radio graphically. Development of renal oncocytoma in pediatric age group is very uncommon with no cases found within our review of the world literature. We report herein the first case of renal oncoytoma in a 14 year old young lady.
