A Rare Case of a Dentinogenic Ghost Cell Tumor Associated With a Compound Odontoma: A Case Report and Literature Review.

A dentinogenic ghost cell tumor (DGCT) is a rare and locally aggressive benign mixed odontogenic tumor, histologically made up of ameloblast-like epithelial islands, ghost cells, and dentin-like material. This is a highly unusual example of DGCT combined with an odontoma in a 13-year-old female patient affecting the right maxilla. On radiographic examination, ill-defined radiolucency with right maxillary sinus obliteration and involvement of permanent maxillary right first and second molars were noted. The second molar was pushed towards the orbital fossa, and root resorption of the first molar is associated with multiple radiopaque masses. The excision specimen showed multiple tooth-like structures histologically, including dentin-like areas and dental pulp. Only five cases of a DGCT with an odontoma have been documented in the literature, making it a very unusual condition.
