title: Malignant presacral teratoma in children.
abstract: Malignant presacral teratoma is a rare tumor seen predominantly in young female children. The introduction of planned multidisciplinary treatment has improved the outlook for patients with this once dismal disease. Six female children were seen at Memorial Hospital with the diagnosis of malignant presacral teratoma. Five children were age 17 mo to 3 yr and the sixth child was 13 yr old at diagnosis. Presenting symptoms included masses in the buttock or groin, constipation, difficulty voiding, and local pain. Pathological features were varied and complex but three had predominantly endodermal sinus features. One child had the malignant presacral teratoma develop 18 mo after successful resection of a benign sacrosoccygeal teratoma in the newborn period. Treatment varied in the six cases since all were referred after failure of treatment elsewhere. All children had surgery, irradiation, and multiple drug chemotherapy. Four of the six children are surviving disease-free, 3 more than 24 mo off treatment. Evolution of treatment up to the present protocol management is discussed.
