Clinicopathological study on three cases of cemento-ossifying fibroma

Three cases of cemento-ossifying f ibroma were studied clinicopathologically. The tumors were found in three males. The patients' ages at their first visits was 14, 43, and 47 years; the mean age was 34.7 years. All three cases occurred in the mandibular molar region. Radiographically, these lesions were demarcated in all cases. X-ray showed mixed radiolucent/radiopaque shadow in all cases. Tumor enucleation and autogenious iliac spongious bone marrow graft were performed in all cases. There were no recurrence cases. Macroscopically, these tumors were unencapsulated. Microscopically, they were composed of fibrous tissue accompanied by various maturation of cementum-like and/or bone-like tissue.
