Oncocytoma of the maxillary sinus.

A case of oncocytoma of minor salivary gland origin of the left maxillary sinus is presented. No previous reports of oncocytoma confined entirely to the maxillary sinus were found in an extensive computerized search (Medline and Cancerline) of the world literature. The diagnosis and management of these histologically benign but locally aggressive tumors occurring in the head and neck are discussed.
