Abstract
Ameloblastic fibroma (AF) is an uncommon mixed benign odontogenic tumor that usually presents in the first two decades of life with no predilection for sex or race. It can present either peripherally or centrally with a majority of the cases presenting in the posterior mandible. Although it usually presents in posterior mandible, we present a case of a peripheral AF in the maxillary anterior gingiva, which has been described rarely in literature. Described are the clinical, radiographic and histologic features and the subsequent surgical treatment for this lesion.
Highlights
Ameloblastic fibroma (AF) is an uncommon tumor representing 2.5% of all odontogenic tumors [1,2,3]
A case is presented of a 19-month-old with AF associated with tooth #E
It is believed to arise de novo during odontogenesis from hyperactive basal lamina without further odontogenic differentiation [2]. It is the least differentiated of the mixed odontogenic tumors because it does not produce any dentin or enamel matrix [2]
Summary
Ameloblastic fibroma (AF) is an uncommon tumor representing 2.5% of all odontogenic tumors [1,2,3]. There have been reports of peripheral (soft tissue) ameloblastic fibro as [4,5]. The majority of these lesions present in the posterior mandible and are associated with an impacted tooth [5,6]. A case is presented of a 19-month-old with AF associated with tooth #E.
