Definition / general
Embryonal carcinoma composed primarily of embryoid bodies
Embryoid body has amniotic cavity-like structure and is continuous with intestinal duct, and rarely has squamous cell nests, while "yolk sac" is continuous with hepatic tissue
Embryoid body is not considered to be a real or teratomatous embryo, but a product of divergent differentiation into intestine and liver from the plastic epithelium, which seems to be derived from embryonic gut (Hum Pathol 1988;19:1144)
