Peripheral osteoma associated with peripheral ossifying fibroma: A case report

Osteoma is a benign osteogenic neoplasm composed of mature compact or cancellous bone and classified as central, peripheral or extra-skeletal. Peripheral type of osteoma is rare. The maxillary sinuses are the most common sites of involvement. It is rare in jaws. Peripheral ossifying fibroma is a reactive lesion of oral tissues, associated with local factors such as trauma or irritation factors. In this paper, we presented the first case of solitary peripheral osteoma associated with peripheral ossifying fibroma. The lesion was located in the lingual surface of the left posterior area of mandible in a 32-year-old woman. The lesion was removed surgically, and no recurrence has been observed after six months follow up.
