Ameloblastic fibroma in one-year-old girl

Abstract

Ameloblastic fibroma (AF) is a relatively rare, slow growing benign mixed odontogenic tumor, comprising of 1.5-4.5% of all odontogenic tumors. It is usually asymptomatic except for the eventual expansion of the jaw. AFs are most common in adolescents and young adults, mostly affecting the mandible as a well-defined uni or multilocular radiolucency. The effective surgical treatment includes enucleation and curettage of the surrounding bone and removal of the affected teeth. Although recurrence of AF is rare, a long term follow up is recommended. This report describes a 1-year-old girl with AF in the mandible and discusses its clinical, radiographic and histological findings.
