Osteoma is a benign tumor consisting of mature bone tissue. It often occurs in the skull and facial bones; however, peripheral osteoma arising in the inferior border of the mandible is relatively rare. We describe a case of peripheral osteoma arising in the inferior border of the mandible in a 17-year-old girl. She had been aware of a swelling at the left side of the mandible for 1 year. Radiographic and computed tomographic examinations revealed a bony mass located in the inferior border of the mandible. A clinical diagnosis of peripheral osteoma was made, because the tumor showed evidence of slow progression and arose unilaterally in a young woman. We surgically excised the tumor via an intraoral approach. The tumor measured 23 × 18 × 15 mm. The histopathological diagnosis was a compact osteoma. The patient has remained free of recurrence for 6 months after surgery.
