Peripheral Dentinogenic Ghost Cell Tumor of the Maxilla.

Dentinogenic ghost cell tumor (DGCT) is an uncommon locally invasive odontogenic tumor, representing 1.9% to 2.1% of all odontogenic tumors. The main microscopic features of DGCT are an ameloblastoma-like odontogenic epithelial proliferation with sheets of ghost cells and dentinoid material formation. The peripheral variant of this clinical rarity, which represents a less aggressive behavior than central lesions, mostly affects the anterior region of both jaws. In this case report, the authors present a DGCT that was observed in the maxillary posterior region in a 59-year-old female patient. The patient presented with pain and nodular swelling in the right maxillary molar region, which extended from the buccal vestibule to the edentulous area. Additionally, there was a destruction of the underlying bone, as seen radiographically. This case report includes the clinical, radiological, and histopathological features of the lesion, which was diagnosed as a peripheral DGCT without any evidence of recurrence in the 2 years after excision.
