Oncocytoma Parotid Gland

Vikas Sharma et al. Ann Maxillofac Surg. 2018 Jul-Dec.

Abstract

Very few cases of parotid oncocytoma have been reported in literature. Because of its rarity (<1% of salivary gland tumors) and clinical presentation of the tumor, there is a tendency among the clinicians to misdiagnose it as pleomorphic adenoma, hemangioma, or other forms of oncocytosis. Only a histopathological examination can confirm it. We evaluate here a case of swelling of the parotid gland in a 70-year-old male who had the tumor for over 9 years to reach a diagnosis. Furthermore, our aim is to bring to the forefront how these lesions require a comprehensive workup and how to choose the best treatment strategy.

Keywords: Fine-needle aspiration cytology; oncocytoma; parotid.
