ABSTRACT The Cemento-Ossifying Fibroma (COF) is a benign intraosseous neoplasm of odontogenic origin. It is locally aggressive and usually manifests as a single lesion in patients between the 3rd and 4th decades of life. In the present study, it was reported a clinical case of COF occurring in a 32-year-old patient, and a narrative literature review on that tumor was also carried out. The review was conducted by using PubMed database, between 1948-2020. Clinical case: the pacient showed up at the Dentistry Hospital of UFU, complaining of a painless volume increased in the left mandible. The tomographic examination showed a mixed density, well demarcated margins and cortical expansion. The lesion was treated by partial mandibular resection, without preserving the basis, followed by an immediate fixation with titanium plate. After 14 months, the patient was submitted to a reconstruction with autogenous grafts from iliac crest. Currently, no recurrence was reported and the patient is waiting for an osseointegrated implant-supported prostheses. The literature review shows that COF is considered as an odontogenic lesion with its genesis linked to the periodontal ligament. The usual related complaint is an asymptomatic, expansive swelling, which may reach great dimensions. With no proven invasion potential, its growth may cause cortical expansion and destruction. The treatment depends on its size and location, being usually conservative. With minimum 12 months follow up, COF presents a low potential of recurrence and a good prognosis for the patient. However, one case of malignant transformation to an osteosarcoma was reported in the literature.
