Abstract:
Teratomas occur infrequently in retroperitoneal areas and are usually benign. They may contain highly organized structures like digits and limbs. The presence of a well-formed fetus in teratomas is extremely rare. This report further documents an instance in which two fetuses were embedded within the retroperitoneal teratoma.
