Abstract

Oncocytoma, also known as oxyphilic adenoma or mitochondrioma of the parotid gland is a rare benign tumor constituting less than 1.5% of all parotid lesions. As there are no characteristic imaging findings, this lesion often poses a diagnostic and clinical challenge. We present a rare case of a parotid oncocytoma posing a diagnostic challenge in a 55-year-old woman presenting with a facial mass. We hope to bring awareness of this benign entity affecting the parotid gland.
