Abstract

Dentinogenic ghost cell tumor (DGCT) is a rare epithelial odontogenic neoplasm, representing 1.9% to 2.1% of all odontogenic tumors. It is the neoplastic counterpart of the calcifying odontogenic cyst (COC), and characteristic islands of odontogenic epithelical cells contain numerous ghost cells and dysplastic dentin, and also have many common histological features with ameloblastoma. The 2005 World Health Organization (WHO) Classification of Odontogenic Tumours re-named this entity as calcifying cystic odontogenic tumor (CCOT) and defined the clinico-pathological features of the ghost cell odontogenic tumours,CCOT, DGCT and ghost cell odontogenic carcinoma (GCOC). We report a rare case of central DGCT in the posterior maxilla of a 31-year-old female with literature review, for the emphasis of Oral and Maxillofacial surgeons role.
