[Endoscopic removal of a mandibular ameloblastic fibro-odontoma].

INTRODUCTION: Ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. It occurs predominantly in children and young adults. This article reports a case of ameloblastic fibro-odontoma affecting a young boy who was treated by endoscopy. CASE REPORT: An 11-month-old child was admitted for a right mandibular rapidly growing mass. Computed tomography confirmed the presence of a large radiopaque mass on the right mandible containing compartmented tooth-germs. A biopsy exeresis was performed to completely remove the tumor with an endonasal endoscope. The histological diagnosis was an ameloblastic fibro-odontoma. DISCUSSION: We performed the enucleation with a nasal endoscope to make sure that the entire lesion had been removed. Bone resection was minimal which should decrease the risk of growth disorders. The ameloblastic fibro-odontoma is a rare mixed odontogenic tumor usually asymptomatic and slow growing. Histopathology proves the diagnosis. The treatment is curettage, preserving the adjacent teeth.
