Central Odontogenic Fibroma of Maxilla: A Rare Case

Central odontogenic fi broma (COF) is a rare benign odontogenic tumor characterized by variable amounts of inactive-looking odontogenic epithelium embedded in a mature fi brous stroma corresponding to 0-5.5% of all odontogenic tumors. COF may be seen at any age, but it is diagnosed most frequently in patients between the second and fourth decades of life. The lesion is asymptomatic except the swelling of the jaw. It occurs slightly more often in the mandible, and the prevalent site in the mandible is the molar-premolar region whereas in maxilla it occurs anterior to the fi rst molar. The periphery usually is well defi ned where smaller lesions are usually unilocular, and larger lesions show a multilocular pattern. The internal septa may be fi ne and straight, as in odontogenic myxomas, or it may be granular, resembling those seen in giant cell granulomas. COF may cause expansion with maintenance of a thin cortical boundary or on occasion can grow along the bone with minimum expansion, similar to an odontogenic myxoma. Tooth displacement is common, and root resorption has also been reported. Here, we present a rare case of COF in the left premolar area of the maxilla in a 14-year-old male.
