L'hyperplasie oncocytaire nodulaire multifocale de la glande parotide

Nodular Oncocytic Hyperplasia of Bilateral Parotid Glands With Parapharyngeal Space Extension

Oncocytic tumors comprise a group of rare benign neoplasm of salivary glands, accounting for less than 1% of all salivary gland tumors. Nodular oncocytic hyperplasia characterized by multiple unencapsulated oncocytic nodules in the salivary glands is an extremely rare condition. We report a case of bilateral nodular oncocytic hyperplasia of parotid glands with parapharyngeal space extension in an 80-year-old woman whose initial presentation was recurrent parotitis. Our case may be the first report of nodular oncocytic hyperplasia in the parapharyngeal space, arising from the parotid gland. The patient underwent total parotidectomy and excision of parapharyngeal tumors using a transparotid transcervical approach, and at the 2-year follow-up, no evidence of recurrence was found.
