Oncocytoma is a rate tumor that is epithelial in origin. Oncocytoma is histopathologically characterized by large “oncocytes” with eosinophilic granular cytoplasm. In the maxillofacial region, this tumor occurs in the minor or major salivary glands. Most oncocytomas occur in the parotid glands; oncocytomas occurring in the submandibular gland, palate, or buccal mucosa are rare.
We report a case of oncocytoma arising in the submandibular gland of a 37-year-old woman. After surgical treatment, the condition of the patient was fairly good. There has been no recurrence after 2 years.
