Oncocytomas arising in the nasal cavity are quite rare. These entities more commonly occur in the major salivary glands, minor salivary glands, respiratory seromucinous glands, and endocrine organs. Very few cases of oncocytoma in the nasal cavity have been reported, with only 5 diagnosed as malignant. This article describes a case involving an 81-year-old man with a nasal oncocytoma that was completely resected with an endoscopic medial maxillectomy. The diagnostic rationale is discussed, along with a review of the literature.
