Abstract
- Ossifying fibroma is a diagnostic designation for fibro-osseous lesion characterized by osteoid rims and osteoblasts lying in irregularly shaped bony trabeculae. We experienced 3 cases of pathologically proven ossifying fibroma. One occured in the gingivobuccal area of an 10-year-old male; another involving the maxillary sinus and alveolus of 22-year-old female and the last one in the ethmoid sinus of 31-year-old female which is unique in its presentation as a cystic mass. Total or near total excision resulted in a disease-free follow-up period of 11 to 26 months. It appeared that ossifying fibroma is demarcated from adjacent cancellous bone and when growing beyond the confines of the involved bone, is separated from the adjacent soft tissue by an expanded and attenuated layer of cortical bone.
