Desmoplastic ameloblastoma: A case report

Abstract

Ameloblastoma is a benign neoplasm derived from enamel organ.1 Several histologic subtypes of this tumor have been described. The desmoplastic variant was first described in detail by Eversole et al2 in 1984. Waldron and El Mofty3 in 1987 described a “hybrid” lesion of desmoplastic ameloblastoma (DA) and conventional ameloblastoma, which they suggested represented a “collision tumor.” Although DA has been accepted as a distinct clinicopathologic entity, some researchers still regard it as a histologic variant of ameloblastoma.
