Abstract
Background:
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.
Methods:
The tumor consisted of polygonal cells with granular eosinophilic cytoplasm packed with swollen mitochondria.
Results:
Scattered tumor cells showed abundant smooth endoplasmic reticulum suggesting that the tumor was of adrenocortical origin.
