PEREZ GARCIA, Silvia; BERINI AYTES, Leonardo  and  GAY ESCODA, Cosme. Ossifying fibroma of the upper jaw: Report of a case and review of the literature. Med. oral patol. oral cir. bucal (Ed.impr.) [online]. 2004, vol.9, n.4, pp.333-339. ISSN 1698-4447.

A number of processes generically referred to as benign fibro-osseous lesions comprise different disorders such as fibrous dysplasia, sclerotizing osteomyelitis and ossifying or cementing fibroma. These processes are all characterized by the existence of a vascular fibroblastic stroma, with the production of a calcified matrix ranging from bone to cementum. Ossifying fibroma involves slow-evolving growth with deforming swelling generally arising in the mandible, with possible early dental displacement. From the radiological perspective the disorder generally manifests as a well defined and delimited, unilocular radiotransparency, as a radiotransparent image with central opacifications, or as multilocular transparencies. The lesions exceptionally can be radiopaque. We present the case of a 22-year-old male presenting for evaluation of a three-month, asymptomatic tumor mass in the anterior sector of the upper jaw. Radiologically, the lesion appeared as a radiotransparent zone surrounded by a poorly delimited sclerotic halo. The definitive diagnosis following surgical resection of the lesion was ossifying fibroma. The case is discussed, and a review is provided of the literature on the subject.

Keywords : Ossifying fibroma; cemento-ossifying fibroma; benign fibro-osseous lesions.
