Central odontogenic fibroma.

Odontogenic fibroma (OF) is a benign odontogenic tumor characterized by various amounts of odontogenic epithelium in a mature fibrous stroma. Two variants can be distinguished: an intraosseous or central OF (COF) and an extraosseous or peripheral. The intraosseous variant is an extremely rare tumor that presents clinical, radiographic, and histopathologic variable findings. A thorough review of the English literature revealed 78 cases of COF so far. Thus, we report an additional case of COF occurring in the maxilla of a 36-year-old woman. In addition, we performed a brief description and discussion of the cases reported in the maxilla and mandible.
