title: Light and ultrastructural studies of renal oncocytic adenoma.
abstract: An asymptomatic renal oncocytoma was found in the upper left quadrant of an eighty-five-year-old woman during a routine physical examination. Ultrastructurally, the tumor was composed entirely of epithelial cells filled with normal and abnormal mitochondria. Selective renal angiography showed two renal arteries supplying a lobulated, highly vascular mass. The mass contained irregular and tortuous vessels without any arteriovenous shunting.
