Dentinogenic ghost cell tumor associated with odontoma: report of a rare case and review of literature.

Dentinogenic ghost cell tumor (DGCT) is an uncommon odontogenic tumor considered to be the solid, tumorous variant of calcifying odontogenic cyst (COC). DGCT is characterized by islands of ameloblastoma-like epithelial cells that resemble the enamel organ, the presence of ghost cells, and dentinoid material. Here, we report a rare case of dentinogenic ghost cell tumor associated with an odontoma in an adult patient and conduct a review of the literature. To the best of our knowledge, there have only been 4 case reports of DGCT associated with odontoma, all of which occurred in children and adults younger than 30 years old.
