A 55 year old man complained of a painless mass at the left maxillofacial region.The mass had continuously grown over 10 years.Upon physical examination a cystic mass with size of 5cm in length with bulging smooth surface was seen on the left maxillofacial region.Computed tomography（CT）scan showed a giant cyst with bone destruction and invasion in the left maxilla,maxillary sinus and nasal cavity.Needle aspiration of the mass yielded 80 milliliter of brown fluid.The excisional biopsy was made which revealed ghost cells and dysplastic dentin that were features of dentinogenic ghost cell tumor.Finally,a dentinogenic ghost cell was diagnosed.
