Ameloblastic fibro-odontoma: a case report.

Ameloblastic fibro-odontoma is a benign epithelial odontogenic tumour with odontogenic mesenchyme exhibiting the histologic characteristics of ameloblastic fibroma and complex odontoma. It is usually associated with developing teeth and occurs predominantly in children and adolescents. In many cases, such lesions are found on radiographic evaluation of patients in whom eruption of teeth is delayed. Ameloblastic fibro-odontoma is generally asymptomatic but may cause swelling and discomfort. This report describes an ameloblastic fibro-odontoma in the posterior mandible of a 26-year-old woman and discusses the histogenesis and clinical features of the lesion.
