Ameloblastic fibro-odontoma differentiating into odontoma: An old concept revised

Abstract

Ameloblastic fibro-odontoma (AFO) is a benign mixed tumor of odontogenic origin. It generally occurs in children and teenagers; however, cases occurring in the elderly have also been reported. Generally, the tumor is asymptomatic and is discovered accidently on a radiograph taken for an unerupted tooth, but examples of large tumors causing jaw swelling have been reported in literature. This article presents a case of AFO causing jaw expansion with pain and lymphadenopathy in a 17-year-old male. As the final diagnosis is always confirmed by histopathology, this case is a unique one diagnosed by clinical and radiographic findings as an odontoma and suggesting the differentiation of an AFO to odontoma.
