Recurrence of central odontogenic fibroma: a rare case

Central odontogenic fibroma (COF) is a rare, benign, painless, slow-growing tumor associated with expansion of the bone cortex. Histologically, it consists of fibrous connective tissue that contains multiple islands of odontogenic epithelium. Some lesions have diffuse spherical calcifications that usually are related to islands or cords of epithelium. The majority of cases respond well to conservative treatment such as enucleation and the prognosis is favorable; recurrences are rare. This article presents a rare case of COF that was located in the anterior region of the maxilla and treated with enucleation; the case recurred five years following the initial treatment.
