Cemento-ossifying fibroma is a true osteogenic neoplasm. It is also called as ossifying fibroma or cementifying fibroma. Small lesions seldom cause any symptoms and are detected only on radiographic examination. Large lesions result in a painless swelling of the involved bone. In radiographic features the lesion most often is well defined and unilocular. It may appear completely radiolucent, or more often varying degrees of radiopacity. It is composed of fibrous tissue that contains a variable mixture of bony trabeculae, cementumlike spherules, or both. Treatment of most lesions generally is enucleation of tumor. However, some lesions which have grown large and destroyed considerable bone, may necessitate surgical resection and bone grafting. This case was the bony lesion that was found by accident in patient with mandibular left body and subcondylar fracture. In radiographic examination, there was a mixed radiolucent and radiopaque lesion in mandibular left body area with fracture line. We treated on mandibular left body and subcondylar fracture and enucleated the lesion on the left body area simultaneously. At surgical exploration, the lesion was well demarcated from the surrounding bone, thus permitting relatively easy separation of the tumor from its bony bed. In histopathologic examination, the lesion contained bony trabeculae and cementum-like spherules within a background of cellular fibrous connective tissue. It finally diagnosed as cemento-ossifying fibroma from the result of biopsy.
