Odontogenic Keratocyst Masquerading as a Dentigerous Cyst in the Maxilla: A Case Report of an Unusual Presentation

Abstract

We encountered a case of an odontogenic keratocyst (OKC) that radiographically mimicked a dentigenous cyst and was associatedwith an impacted maxillary third molar. The common OKC location is in the mandible, with a lateral radiolucency. The attachment ofthe radiolucent mass to the coronal surface of the tooth in a maxillary molar is clinically highly unusual. The finding was pathologicallyconfirmed after an excisional biopsy. The clinical and radiographic presentation is different than the typical description of OKC.
