Abstract
The WHO defines primary intraosseous squamous cell carcinoma of the jaw as squamous cell carcinoma arising in the jaw bone which has no continuity with the oral mucosa at an early stage, and it presumably arises from odontogenic epithelial debris and is not due to metastasis from other organs. Many reports have been so far published concerning this carcinoma in the field of oral surgery, but no such studies have been reported in the otorhinolaryngology field. We treated a patient with primary intraosseous squamous cell carcinoma of the mandible which was advanced at the time of detection. It was not controlled by surgical treatment with postoperative radiotherapy, and the patient died. This case is reported herein together with a discussion of the relevant literature.
