Not gastroschisis or omphalocele or anything in between: a novel congenital abdominal wall defect.

Congenital abdominal wall defects occur when normal embryonic development is interrupted and most commonly results in gastroschisis or omphalocele. Other entities, such as ruptured omphalocele, vanishing gastroschisis, and patent omphalomesenteric ducts with prolapse, have also been described and can create a confusing picture. This case of a newborn with a midline abdominal defect and a mass that was intestine-like and arose from the bowel cannot be classified, and no similar reports were found. This suggests a previously undescribed abdominal wall defect with an aberrant colonic appendage.
