Abstract
Sacrococcygeal teratoma (SCT) is the most common congenital tumor in neonates. SCT may be benign (mature and immature) or malignant. Malignancy is rare in SCT diagnosed before 2 months of age. Here, we describe a neonate having a mature teratoma with a focus of malignant yolk sac tumor within and the difficulties faced in its management.
Highlights
We describe a rare case of a mature teratoma with a focus of malignant yolk sac tumor within in a neonate and the difficulties faced in its management
The imaging of sacral tumors in children is valuable to look for foci of malignancy
Loss of planes between tumor and surrounding tissue, sacral invasion and metastases are suggestive of malignancy
Summary
SCT may be benign (mature and immature) or malignant. Malignancy is very rare in infants less than two months of age (7% in boys and 10% in girls) [1].Yolk sac tumors (YST) are rare and highly malignant tumors, occurring in children as well as in young adults.
