Ameloblastic fibro-odontoma of the maxilla: case report.

A 7-year-old girl presenting with proptosis was referred for management of a partially ossified mass occupying the right maxillary sinus. A complete enucleation was performed after the histological diagnosis given in frozen section as ameloblastic fibro-odontoma. Ameloblastic fibro-odontomas occur predominantly in children and young adults. The mandibular molar-ramus area is the favored location and radiographically, these lesions are well circumscribed and lucent-opaque. The tumor mass is composed of a myxoid connective tissue with strands of odontogenic epithelium and differentiated tissues such as enamel and dentin. The treatment is a conservative surgical procedure due to benign biological behavior.
