Abstract

Osteoma is a benign tumor and rarely arises peripherally on the mandible. A case of peripheral osteoma arising on the left coronoid process of the mandible was reported.<BR>A 65-year-old woman was referred to our department. Her chief complaint was swelling of the left cheek. Radiological examination revealed a well-defined, round radiopaque mass (about 2cm in diameter) on the left coronoid process of the mandible. Clinically, a peripheral osteoma was suspected. Under general anesthesia, the tumor was resected by the intraoral approach. This histopathological examination revealed compact osteoma.
