Peripheral osteoma of the mandible with radiologic and histopathologic findings

Abstract

Osteomas are benign, slow growing osteogenic tumors. They are often occurring in the craniofacial bones but rarely originates from the mandible. Osteomas have three varieties as central, peripheral and extraskeletal. Central and peripheral osteomas are often seen in the facial bones. Peripheral osteoma often located in the frontal, ethmoid and maxillary sinus, but rarely occurs in the jaws. Usually they are asymptomatic and discovered incidentally during radiological and clinical examinations. Osteomas are characterized with well-defined, rounded or oval radiopaque mass in the computed tomography. Herein, we report a rare case of peripheral osteoma of the lower part of the mandible in a 19-year-old female with radiologic and pathologic findings.
