A 53-year old man was found to have a right incidental adrenal mass measuring 5 × 6cm. The patient underwent laparoscopic right adrenalectomy and the tumor was surgically removed. The histological diagnosis was oncocytoma, the cytoplasm of which was intensely eosinophilic with abundant granule. Oncocytoma of the adrenal gland is rare disease.Recently, the advancement of imaging techniques, especially the routine use of computed tomography (CT) and magnetic resonance imaging (MRI) lead to increased number of incidentally discovered adrenal masses including adrenocortical oncocytoma. In this report, the clinical features of adrenocortical oncocytomas are discussed.
