Large but benign adrenal mass: Adrenal oncocytoma.

Adrenal incidentalomas of more than 4 cm size are usually malignant. We describe a 28-year-old woman with a 7-cm, non-functioning, well-demarcated adrenal mass, which was identified as an oncocytoma on histopathological examination. Therefore, a large, non-functioning, unilateral adrenal mass with preserved tumor outline should invoke the suspicion of oncocytoma, which is invariably a benign tumor.
