The lesion was diagnosed as a central odontogenic fibroma an uncommon benign neoplasm derived from dental apparatus and was removed by curettage. The patient remains asymptomatic after thirteen years of follow-up which supports the claimed indolent behavior of this poorly documented disease and the adequacy of a conservative surgical treatment. Introduction Central odontogenic fibroma COF is an uncommon benign neoplasm composed by varying amounts of inactive-looking odontogenic epithelium embedded in a neoplastic mature and fibrous stroma 1-12 . The lesion may evolve from a dental germ dental papilla or follicle or from the periodontal membrane and therefore is invariably be related to the coronal or radicular portion of teeth 2 3 . Due to its non-exclusive histological features this lesion may be confused with other entities such as hyperplastic dental follicles odontogenic myxomas and desmoplastic fibromas which highlight the importance of clinicopathological correlation in the diagnosis of odontogenic fibromas 2 3 7 12 13 . Finally there is little information regarding long term results after surgical treatment of this lesion. We describe a COF in the right canine premolar area of the mandible in an adult male. In addition we discuss relevant issues about the origin diagnosis and management of the present lesion. Case report A 28-year-old man presented with a painless periodontal swelling in the right side of the mandible. The patient reported five years of evolution with moderate .
