The ameloblastic fibro-odontoma is an infrequently encountered mixed odontogenic tumor. There has been much discussion in the literature regarding its proper classification. It is characteristically slow growing and asymptomatic, and occurs most commonly in the posterior region. It shows a slight predilection for boys with a mean age of roughly 10 years. A case in a 9-month-old boy of an exophytic, rapidly growing ameloblastic fibro-odontoma of the anterior maxilla is reported.
