ABSTRACT
Sacrococcygeal teratoma (SCT) represents the commonest tumor in the fetus [1], with an esteemed incidence at birth of 1:35000–40000 and a definite female predilection (M:F ratio of 1:4). SCT arises probably from the pluripotent cells of Hensen’s node [2], which is located anterior to the coccyx. Considering these cells migrate into the embryo’s tail during the first postconceptual week, this theory may explain why teratomas arise more frequently in the lower spinal area than in other parts of the body.
