ABSTRACT
Embryologically, Sacrococcygeal teratomas (SCTs) arise from totipotent primordial endodermal germ cells, but they may contain tissues originating from all three germ layers, including dermal elements (e.g. skin), muscle, glial tissue, intestinal mucosal, and pancreas. Routine use of serial prenatal ultrasound has increased the detection of SCT and allowed for accurate identification of site and details of intrapelvic extension or urinary tract obstruction. Routine use of serial prenatal ultrasound has increased the detection of SCT and allowed for accurate identification of site and details of intrapelvic extension or urinary tract obstruction. Laparoscopy can be used for the ligation of the median sacral vessels the resection or mobilization of intra-abdominal or pelvic portions of the SCT. Beyond the immediate postoperative care period, careful monitoring is required as malignant germ-cell tumors can recur either from missed malignant elements in the original tumor or from malignant conversion of benign residual tissue.
