title: Coexisting non-functioning pheochromocytoma and renal oncocytoma: a case report and review of the literature.
abstract: We report a case of an oncocytoma, coexisting with a non-functioning pheochromocytoma in a patient who was operated on for suspicion of a renal tumor with metastases to the ipsilateral adrenal gland. As oncocytoma is a relatively rare lesion of the kidney, estimated to account for approximately 3-5% of renal neoplasms, its coexistence with non-functioning pheochromocytoma, to the best of our knowledge, has not hitherto been described in the medical literature.
