Desmoplastic ameloblastoma of the mandible.

The Desmoplastic Ameloblastoma exhibits important differences in anatomical distribution, histologic appearance and radiographic findings compared with the classic type of ameloblastoma. We describe a case of desmoplastic variant of ameloblastoma localized in the mandibular anterior portion of the jaw, extending posteriorly in the left side. The tumor was expansile, slowly growing and painless. The radiographic finding showed diffuse, radiolucent lesion with cortical bone expansion. Surgical excision was performed and follow-up examination done after two years disclosed no recurrence. The purpose of this article is to assist in better understanding of this variant of odontogenic tumor.
