Multifocal nodular oncocytic hyperplasia of the parotid: case report

Multifocal nodular oncocytic hyperplasia of salivary glands is a tumor-like lesion that occurs predominantly in the parotid gland. The differential diagnosis of the clear cell variant includes many malignant salivary gland tumors. We report the case of a 66-year-old woman who was referred for a left total parotidectomy allowing the final diagnosis of clear cell multifocal nodular oncocytic hyperplasia. The differential diagnoses and histopathogenesis of this rare entity are discussed.
