Abstract: Ghost cell odontogenic carcinoma(GCOC) is a rare malignant tumor originating in the jawbone, which can exhibit clinically and radiographically malignant features distinct from benign odontogenic tumors, such as large tumor size and adjacent bone destruction, but these features lack specificity; therefore, diagnosis often relies on pathological morphology. Characterized by abnormal keratinized ghost cells, small basaloid cells, and dentin-like deposits, accurate identification of GCOC holds significant clinical importance and is beneficial for patient prognosis. This paper reported a case of GCOC in the left maxilla and reviewed the relevant literature.

Key words: Maxillary tumor, Odontogenic tumor, Ghost cell odontogenic carcinoma, Pathological feature
