Unusual content of omphalocele: a congenital mature cystic teratoma of falciform ligament of the liver.

Omphalocele is a congenital midline abdominal wall defect that results in herniation of intraabdominal contents covered by a lining of peritoneum and amnion. The severity of the defect often ranges from a minor herniation of the umbilical cord to a significant protrusion that includes large proportions of intestine and liver. We report unusual content of omphalocele that is congenital mature cystic teratoma of falciform ligament of liver which was confirmed by histopathology. This is a very uncommon entity and not described in world literature.
