Ossifying fibroma is one of a group of fibro-osseous lesions which arises typically within the jaw bones and only rarely affects the long bones. Ossifying fibroma of the long bones almost involve exclusively the tibia but may also involve the fibula. Ossifying fibroma of the long bones is distinct from fibrous dysplasia, adamantinoma and nonossifying fibroma with regard to age of the patient, site, radiographic appearance, histological features, and clinical course. We are reporting the cases of seven patients with a tumor-like lesion that named osteofibrous dysplasia. It is most commonly found in the tibia and fibula of a child ten years of age or younger. Of the seven cases reported in this study, only one patient was younger than ten years. In all cases, the lesions were usually located in the tibial diaphysis. The average duration of clinical manifestation was 5.2 years. The clinical symptoms were anterior bowing of the tibia in 2 cases, buldging of the tibia in 2 cases, and mass overlying the tibia in 3 cases. On the roentgenography, it shows multiple radiolucent lesion with intervening sclerotic rim of the tibial diaphysis. In seven patients, 6 cases were confirmed with biopsy. We had done curettage and bone graft in three cases, VFG was done in one case. The other three cases underwent conservative management.
