Popis: We report a case of gastroschisis in which a paraumbilical band was found at the right margin of the abdominal wall defect and extended into the antimesenteric side of the small intestine. The band consisted of 2 thin cords. Microscopically, 1 band showed a fibrous tissue, and the other 1 revealed a unique vascular structure resembling the vitelline artery and vein, suggesting that the paraumbilical band represents a remnant of the yolk stalk that failed to be incorporated into the umbilical stalk. The origin of the paraumbilical band and an associated pathogenetic hypothesis of gastroschisis are discussed.
