A rare case of osteosarcoma originating in the base of the skull was reported. The patient was a 38-year-old woman who had multiple cranial nerve paralysis on the right side. She showed a marked swelling of the right epipharyngeal region without palpable neck masses. Repeated histological examinations revealed chronic inflammation but did not reveal malignant tumor. Clinical findings, radiographic findings, CT scan, Ga scintigraphy and bone scintigraphy strongly indicated a malignant tumor of the epipharynx. She then received telecobalt irradiation of 6000 rads with no improvement. Final histological examination revealed the osteosarcoma of the epipharynx. She died from brain stem metastasis of the tumor. Literature related to osteosarcoma of the head and neck region are reviewed.
