Large Omphalocele with Limb Deficiency

Omphalocele is defined as herniation of abdominal contents into the base of umbilical cord and covered by a membrane. Large omphalocele contains liver. We report a case of twin pregnancy (monochorionic diamniotic) with one stillborn anomalous fetus, whereas the other was a live-born preterm low birth weight baby. The anomalous baby had a herniated sac at the insertion of umbilical cord covered by a membrane and absent left upper limb. Content of herniated sac included liver with part of it outside the sac. Microscopic examination of the membrane showed a layer of amnion.
