Ameloblastic fibroma is generally classified in an odontogenic mixed tumor, which is much less common than the ordinary type of ameloblastoma. The authors studied a case of this tumor by means of histological and electron-microscopic techniques. The patient was a 10-year-old male, with a diffuse swelling of the gingiva at the left premolar region of the mandible. By roentgenographic examination, a unilocular hen-egg-sized radio-lucent area was observed in the region from the lateral incisor to the first premolar of the left mandible. 15 months after marsupialization, ossification was seen in the roentgenogram, so a peripheral osteotomy was performed. The postoperative course was uneventful and during the 37-month interval since surgery, there has been no evidence of recurrence. Pathological examination revealed ameloblastic fibroma.
