Context: Dentinogenic Ghost Cell Tumor (DGCT), a solid variant of the Calcifying Odontogenic Cyst (COC), is an uncommon odontogenic neoplasm occurring predominantly in later life with locally aggressive behavior characterized by ameloblastoma-like islands of aberrant keratinization of odontogenic epithelium in the form of ghost cells in association with dysplastic dentin. It accounts for only 2–14% of all COCs. Case Report: We report a case of 21 year old male patient with chief complaint of swelling in left upper back tooth region since 4-5 months and histopathologically characterized by ghost cell with strands and cluster of odontogenic epithelium in mature connective tissue stroma. associated with in dentinoid formation are some areas. Conclusion: The present case of 21-year-old male was diagnosed as DGCT, a timorous form of COC, due to its characteristic histological features; numerous ghost cells and dentinoid material.
