Intracranial chordoma is very uncommon and rarely invasde the oral area.<BR>This is a report of a case with recurrent cranial chordoma, which is diagnosed from biopsy specimen of cheek tumor.<BR>A 43-year-old female visited the department of Dentistry, Matsue Red Cross Hospital on August 18, 1986. She complained of facial spasm and left cheek swelling. Ordinary X-rays (P-A View, Panorama View) demonstrated partial defect of left temporal bone by resection of cranial chordoma 6 years before. The cheek region was suspected to be something like benign tumor involving the facial nerve.<BR>But computed tomography findings showed a continuous mass extending from intracranial to pharynx. An intra-oral biopsy specimen showed large-sized physaliphorus cells, then she was diagnosed as recurrence of cranial chordoma with cheek invasion.<BR>Cheek tumor was reduced under local anesthesia and facial spasm disappeared after reducion. This should be the first report from oral region of this tumor in Japanese literature.
