Immature Sacrococcygeal Teratoma with Microfoci of Yolk Sac Tumor in a Preterm Female NewbornIs the Surgical Resection Enough?

Sacrococcygeal teratoma (SCT) is the most common neoplasm in neonates and the most common germ cell tumor in children. SCT with malignant elements is very rare in infants. Prenatal diagnosis is of exceptional importance for the adequate fetal intervention, evaluation of perinatal complications and the selection of the optimal treatment. The treatment of choice is complete surgical resection. Postsurgical approach for immature teratoma with malignant elements is not well established. Considering the risk for tumor recurrence, long term follow-up is mandatory. We report clinical, laboratory, radiological and histological findings, surgical procedure, and follow-up in the preterm female neonate with immature SCT with malignant elements.
