Background. Cemento-ossifying fibroma (COF) is a relatively rare tumor of the maxillary bones, classified among the fibro-osseous lesions Feller et al. (2004). The lesion that develops appears within the bone, although in some cases, it involves the soft tissues Kaufmann et al. (1999), Jung et al. (1999). In literature there is not report of COF in the thickness of the cheek. Methods. A 24-year-old Caucasian woman presented a hard mass of 1.5 cm in the thickness of the right cheek; no signs of damaged tissues were present. Radiographically all the mass appeared radiopaque as bone, and well demarcated with an evident capsule, without invasing the adjacent structures. The lesion was resected en bloc. Result. Pathological examination of the excised mass revealed an encapsulated cemento-ossifying fibroma that did not invade the adjacent tissues. The case was resolved with no complicance and with restitutio ad integrum. Conclusion. Typically, the unusual characterisitcs of a pathology get difficult as for its diagnosis and therapy. This is a case report of a rare cemento-ossifying fibroma of the cheek. Clinical and instrumental examinations exclude a malignant pathology and lead to an appropriate conservative surgical therapy. Only the histological examination confirmed the clinical diagnosis of extraosseous COF.
