抄録

Desmoplastic ameloblastoma was first described by Eversole in 1984. We recently encountered a case of desmoplastic ameloblastoma in the anterior maxilla.
A 52-year-old man presented to the First Department of Oral and Maxillofacial Surgery of Meikai University. A biopsy was performed, and examination of the biopsy specimen indicated a diagnosis of odontogenic fibroma. The patient underwent tooth extraction in the affected region and tumor resection under general anesthesia.
Microscopic examination after the operation showed an extensive collagenized stroma containing small islets of tumor epithelium with a slight tendency to from cystic structures. The histological diagnosis was thesefore desmoplastic ameloblastoma.
