Central odontogenic fibroma (COF) is a rare tumor that accounts for 0.1% of all odontogenic tumors. It has been defined as a benign neoplasm, which appears in the jaw. Clinically, the lesion grows slowly and leads to cortical expansion. Radiologically, the most common finding is multilocular radiolucency. In some cases, it may be associated with root resorption or displacement. Histologically, the lesion is characterized by mature collagen fibers and numerous fibroblasts. COF responds well to surgical enucleation with no tendency for malignancy or recurrence. Here, a case of central odontogenic fibroma of the mandible in a 71-year-old man is described. The lesion was an asymptomatic mass with well-defined borders covered by normal mucosa. The lesion presented as a multilocular radiolucency in relation to the root of the canine. The lesion was surgically removed and analyzed histopathologically. There were no postoperative complications. (J Oral Sci 51, 457-461, 2009)
