Suprasellar Malignant Teratoma with 11-year Survival —Case Report—

抄録

Long-term survival of malignant teratoma is rare. A 16-year-old female with a suprasellar malignant teratoma survived for 11 years before succumbing to embryonal carcinoma. A suprasellar immature teratoma with increased serum alpha fetoprotein level was verified histologically. Radiation therapy and combined chemotherapy were given after partial removal. Eleven years later, the primary lesion recurred as embryonal carcinoma.
