Desmoplastic ameloblastoma in the maxilla: A case report and review of literature

Abstract

Desmoplastic ameloblastoma (DA) is a rare variant of ameloblastoma (AM). The location of this lesion, its histology and radiological features differ from those of conventional AM. We report a case of DA in the canine / premolar region of the left maxilla of a 32-year-old woman and present a brief review of the literature. Radiographically, it had a mixed radiolucent / radiopaque appearance with ill-defined margins. Histologically, the tumor was characterized by extensive stromal desmoplasia and small tumor islands of odontogenic epithelium in the stroma, along with a few areas of reactive bone formation. The tumor was treated by partial maxillectomy and the patient was disease free after 1 year.
