A Rare Case of Multifocal Cystadenomatous Oncocytic Hyperplasia of the Parotid Gland

Multifocal cystadenomatous oncocytic hyperplasia of the parotid gland is an extremely rare non-neoplastic lesion. We present a case involving a 73-year-old female with a painless, small mass in her right preauricular region for the past two months. Fine needle aspiration suggested a diagnosis of mucoepidermoid carcinoma. Following further investigations, the patient underwent an uneventful right superficial parotidectomy without neck dissection. Histopathological examination of the excised superficial parotid tissue revealed multifocal cystadenomatous oncocytic hyperplasia with negative surrounding margins. The patient's subsequent follow-ups in the outpatient department were satisfactory, with no reported issues, concerns, or evidence of recurrence.
