Oncocytic cell neoplasms are usually found in the thyroid or salivary glands and the kidneys. Adrenal oncocytoma (AO) is an extremely rare localization. It is often non-functional and the suspicion of malignancy is considered when the size of an adrenal incidentaloma is greater than 4 cm. These adrenal oncocytomas, however, are large, round, and encapsulated with a benign presentation and evolution. We report on a 40-year-old male patient. Upon suspicion of a SARS-CoV-2 infection, the general physician instructed a chest CT scan, which, fortuitously, revealed a suspicious left adrenal lesion measuring 62x45mm. A biochemical investigation was negative for either pheochromocytoma or Cushing's syndrome, allowing the recommended surgery to be performed. The anatomopathological analysis showed an uncommon benign adrenal lesion, an adrenal oncocytoma.
