Abstract

The case of a benign oncocytoma arising in a patient from retroperitoneal heterotopic adrenocortical tissue is reported; this tumor was found in a 44-year-old man. The tumor consisted of polygonal cells with granular eosinophilic cytoplasm packed with swollen mitochondria. Scattered tumor cells showed abundant smooth endoplasmic reticulum suggesting that the tumor was of adrenocortical origin.
