AMELOBLASTOMA OF THE ANTERIOR MANDIBLE: A REPORT OF 2 CASES

Abstract

Ameloblastoma is an epithelial odontogenic tumor that primarily affects the posterior mandible in patients from 20 to 60 years of age. It usually presents as a well-defined, unilocular to multilocular radiolucency with associated expansion of the jaws. Ameloblastoma arising from the anterior mandibular region is rare. We report 2 cases of ameloblastoma affecting the anterior mandible. The first case is a 59-year-old male patient with a swelling of 1 year duration, and the second is from a 74-year-old female with a painless swelling and tooth mobility lasting 2 years. Panoramic radiography showed in both cases a well-defined multilocular radiolucency with thin corticated borders. Microscopic analysis of both cases revealed islands of odontogenic epithelium with central stellate reticulum-like areas and peripheral ameloblastic areas, arranged in a follicular pattern. The treatment was surgical resection, and no evidence of recurrences was observed.
