Abstract :
Proliferations of oncocytes in salivary glands are categorized as oncocytic metaplasia, nodular or diffuse hyperplasia, oncocytoma, and oncocytic carcinoma. Multifocal nodular oncocytic hyperplasia of the parotid gland represents an extremely rare lesion that refers to tumor- like nodules that show hyperplasia of metaplastic oncocytes. n this article, we present a case of a multifocal nodular oncocytic hyperplasia in a 60 year old woman with a 7-months history of gradually increasing diffuse swelling of the left parotid gland. The histopathological features and differential diagnosis of this rare lesion is described and discussed.
