A Cases of Endodermal Sinus Tumor in Sacrococcygeal Region / 대한정형외과학회잡지

ABSTRACT

A endodermal sinus tumer (Teilum) is a highly malignant germ cell tumor showing a selective overgrowth of yalk sac endoderm intimately associated with the extraembryonic mesoblast. Several cases of the tumor originating from the ovaries have been reported in the literature. We present a case of the tumor with a rare origin from the sacrococcygeal region.
