Abstract

Dentinogenic ghost cell tumor (DGCT) is a rare neoplasm, representing 1.9% to 2.1% of all odontogenic tumors. Peripheral DGCTis a rare tumor with only 25 cases previously described in the English literature. The majority of cases have been reported to occurin the anterior part of the jaws. A rare case of peripheral DGCT is reported, located in the lingual side of the anterior mandibleof a 68-year-old man. The patient presented a pedunculated painless growth of 1.5cm in diameter. Radiographically, no bone involvementwas found. The lesion was excised and histologically characterized by islands of epithelial cells showing ameloblastoma-like featureswithin fibrous background tissue. Dysplasic dentin and ghost cells with calcifications were frequently observed. Areas showing a connectionbetween tumor cells and the overlying mucosa were also identified.
