Congenital tumor arising from the tailbone region that may require fetal surgical intervention in severe cases.
Full Definition
Sacrococcygeal teratoma (SCT) is the most common tumor in newborns, arising from pluripotent cells near the coccyx. Large tumors can cause high-output cardiac failure in utero due to vascular steal, leading to hydrops fetalis and intrauterine demise. Fetal intervention, including tumor debulking or vascular ablation, may be considered for cases with evidence of cardiac decompensation before viability.
Usage
