The management of cervical adenosarcoma in a 14-year-old girl is described. The tumor had an exceptionally violent biological nature and did not respond to a variety of customary and unorthodox therapeutic measures. These included conventional intravenous chemotherapy, radiation therapy, surgery, intraarterial chemotherapy, colostomy, and peritoneovenous shunt for untreatable ascites. The patient died within 16 months of diagnosis. This is the fifth case of cervical adenosarcoma in the English literature. This tumor usually has a better prognosis and none of the previous four cases succumbed to the disease. The unusual virulence of the present case is discussed and the literature reviewed.
