Cemento-ossifying fibroma (COF) is a clinicopatological variant of ossifying fibroma which is benign fibro-osseous neoplasm affecting jaw or cranial skeletons. It is also called central ossifying fibroma. COF is a slow-growing tumor and occurs exclusively in the tooth bearing areas of the jaws. This tumor particularly affects adult female and rarely occurs in children. Here we show a rare case of COF involving the anterior mandible in an 8-year-old girl. She was referred to our department with painless and hard swelling of the mandibular symphysis. Computed tomography (CT) showed that well circumscribed and mainly radiodense lesion with radiolucent areas expanded the inferior border of the mandible. The size of this lesion is 35 × 30 × 24 mm. Pathological diagnosis was COF. She had underwent two times of surgery for tumor enucleation through an intraoral approach, and after that, we removed bilateral central incisors with residual tumor around the roots. There has been no sign of recurrence 1 years after the last surgery. We have continued follow-up observation.
