Full Definition
Sacrococcygeal teratoma (SCT) is a rare congenital tumor that develops at the base of the spine in the coccyx region. These tumors arise from totipotent cells and can contain tissues from all three germ layers, including neural, gastrointestinal, and respiratory elements. SCTs are classified into four types based on their location and extent of internal versus external components. Large tumors can cause complications including polyhydramnios, fetal hydrops, and high-output cardiac failure. Prenatal diagnosis allows for specialized delivery planning and immediate postnatal surgical intervention when indicated.
