title: Long bone ossifying fibromas.
abstract: Ossifying fibromas involving the tibia were seen in two patients. In both patients, the radiographic appearance of the lesions suggested fibrous dysplasia, but histopathologic evaluation demonstrated findings similar to ossifying fibroma of the mandible and facial bones. Radiologic and pathologic recognition of this entity is necessary for proper treatment.
