Oncocytic tumors of the major salivary glands are rare, accounting for less than 1% of all salivary gland tumors. When they do occur, these neoplasms typically present as solitary nodules that affect only one major salivary gland, usually the parotid. Multiple bilateral multinodular tumors are rare. We report the case of a 53-year-old woman with a case of synchronous multiple bilateral multinodular oncocytomas that arose in a background of bilateral oncocytic nodular hyperplasia in the parotid glands. The patient underwent superficial parotid resections, and at the 4-year follow-up, she exhibited no evidence of recurrence.
