Oncocytic adrenal cortical neoplasm of uncertain malignant potential – A rare case report

ABSTRACT

Adrenal oncocytic tumors are rarely encountered. Most of the oncocytic tumors are benign and rarely malignant. Here we report a case of a 10-year-old male child presented with abdominal mass whose Contrast-Enhanced Computed Tomography (CECT) shows well-circumscribed tumor. Right adrenalectomy was carried out. Histopathologically, it was diagnosed as adrenal cortical oncocytic neoplasm of uncertain malignant potential (AONUMP). This case highlights that although adrenal oncoytic tumors are rare, we should consider this as a differential diagnosis while evaluating the patient for adrenal masses. The case is presented in view of its rarity, and distinguishing gross and microscopy appearance, the diagnosis of which was further confirmed with immunohistochemistry markers.
