Cemento-ossifying Fibroma: Report of Two Interesting Cases

Cemento-ossifying fibroma is a fibro-osseous lesion that has benign neoplastic behavior. We report two cases of cemento-ossifying fibroma (COF) and review the literature in order to study the imaging findings of COF. It is almost unavoidable that diagnosis of fibrous dysplasia from COF will be complicated by the fact that some pathologic features are shared by both lesions. So the final definitive diagnosis requires evaluation of the radiographic features.
