Cemento-ossifying Fibroma of the Mandible: A Benign but Potentially Destructive Tumor

Cemento-ossifying fibroma (COF) is a benign fibro-osseous tumor containing variable amount of mineralized tissue resembling bone or cementum. Microscopically it exhibits actively proliferating fibroblasts with varied cellular pleomorphism and mitotic activity. We present a case of a woman referred for eva luation of bony swelling in the lower half of the face. The mass had first appeared 3 years ago and was growing larger. The clinical, radiological, histopathology and the successful surgical management of the case is discussed here.
