Adrenocortical oncocytoma -- a rare tumor of undefined malignant potential: report of a case

Abstract

Adrenocortical oncocytomas are exceptionally rare. To our knowledge, only 23 cases have been reported in the world literature, most of which were benign and nonfunctioning. We report a case of adrenocortical oncocytoma diagnosed by pathological examination of an extirpated right adrenal mass in a young woman. We discuss this case and review the literature on this unusual entity.
