Adrenocortical oncocytoma

ABSTRACT

Adrenocortical oncocytoma is an exceedingly rare pathological variant of an adrenal neoplasm. The pathogenesis of oncocytic neoplasms is poorly understood. Females have been reported to be affected 2.5 times more frequently than males, and left-sided lesions are more common than those on right side. This case describes a 20 years old female with right lumbar pain. She found to have a right adrenal gland mass measuring about 6 x 5 cm. A computed tomogram showed hypodense mass lesion 6 x 4.2 cm involving right adrenal gland. Differential diagnosis of non-functional adrenal adenoma was made. A laparoscopic right adrenalectomy was performed using the 3-ports lateral transperitoneal approach. Histopathology showed adrenocortical oncocytoma of adrenal gland
