Ameloblastoma arising in the wall of dentigerous cyst: Report of a rare entity

Sudheer Kanth Kondamari et al. J Oral Maxillofac Pathol. 2018 Jan.

Abstract

Dentigerous cyst (DC) is a developmental odontogenic cyst that encloses the crown of an unerupted tooth by expansion of its follicle with accumulation of fluid between the reduced enamel epithelium and the tooth crown and is attached to the neck of the tooth. The lining of DCs shows a potential for neoplastic transformation to ameloblastoma, squamous cell carcinoma, and mucoepidermoid carcinoma. Here, we report a rare case of an ameloblastoma arising in the wall of a DC.

Keywords: Ameloblastoma; dentigerous cyst; neoplastic transformation.
