Subperiosteal Osteoid Osteoma: A Rare Entity

Osteoid osteoma (OO) is a relatively frequent benign tumor of the bone which has seldom been described in the jaws. It was originally described by Bergstand in 1930 and recognized as a distinct clinical entity by Jaffe in 1935. It is composed of osteoid and woven bone, and surrounded by a halo of reactive sclerotic bone, with an average size of the nidus less than 1.5 cm. The lesion occurs predominantly in children, adolescents and young adults. It accounts for 3% of all primary bone tumors, and about 10% of benign bone tumors. About 80% cases of OO occur in long bones while less than 1% occurs in head and neck region. The most common site is in the skull. When affecting the facial bones, they are frequently found in the mandible, the most common location being the posterior lingual surface and the mandibular angle area. Herein, we report a rare case of OO of the mandible in a 16-year-old male patient with a brief literature review. How to cite this article Rathod SV, Patel S, Pathak J, Swain N.
