We report an extremely rare case of peripheral osteoma occurring in the maxilla and associated with bony swelling in the subcutaneous nasal vestibule. A 66-year-old man was referred to our department because of a painless swelling of the left nasal vestibule. Intraoral examination revealed a firm, bony, round swelling in the left maxillary gingivolabial fold. Radiographic and computed tomographic examinations demonstrated that the lesion was radiopaque with well-defined margins and a narrow region in contact with the maxilla. The patient received surgical resection of the maxillary tumor under general anesthesia. Histopathological examination revealed areas of mature compact bone formation diagnosed as osteoma. This is an extremely rare report of peripheral osteoma arising in the nasal vestibule. At present, the patient is well and has had no recurrence of the tumor.
