Abstract

Sacrococcygeal teratoma (SCT) occur in approximately one per 40,000 births and the most common congenital tumors in the newborn. Most SCT are external and extend outward from the lower part of the sacrum and buttock. Although these tumors are usually benign, malignant degeneration is common and the rate increases as fetal age. SCT identified in utero is associated with 50% fetal demise, which is caused by hyperdynamic cardiac failure, hemorrhage, and polyhydramnios induced preterm labor. Therefore the early prenatal diagnosis and treatment are very important. We report a case of SCT which was diagnosed by ultrasonography at 35 weeks` gestation and was delivered by cesarian section at 39 weeks` gestation with a brief review of literatures.
