Abstract: Dentinogenic ghost cell tumour is a rare odontogenic tumor with local invasiveness. Clinical and imaging studies are not specific, especially when there are few tissues submitted for inspection or insufficient materials are obtained. It is easy to miss the diagnosis. A case of dentinogenic ghost cell tumour in the posterior maxillary bone of a teenager is reported, and the retrospective analysis is made to improve the understanding.

Key words: dentinogenic ghost cell tumour, missed diagnosis
