Diagnosis of ameloblastic fibro-odontoma: case report

Abstract

Objective: the present report describes the clinical, radiographic, and histopathological features of an ameloblastic fibro-odontoma (AFO) lesion. Case report: we report a clinical case of a 14-year-old boy with asymptomatic edema. Panoramic radiography detected a unilocular lesion with defined margins located in the posterior region of the mandible. The internal structure of the lesion presented several degrees of radiopacity with the involvement of the third molar. Cone-beam computed tomography revealed expanded buccal and lingual cortical bones, perforation of the lingual cortical bone, and displacement of the mandibular canal. AFO was suspected based on the radiographic and clinical characteristics. Total excision was performed and histologically examined, confirming the diagnosis of AFO. No recurrence occurred during a 24-month follow-up period. Final considerations: the evaluation of the clinical, radiographic, and histopathologic findings needs to be accurate for a correct diagnosis and appropriate treatment for case of AFO since the presentation is often asymptomatic.Keywords: odontogenic tumors; radiography panoramic; cone-beam computed tomography.
