title: Isolated well-formed intestinal tissue in the umbilical cord. A variant of cyst of omphalomesenteric duct.
abstract: An extremely rare abnormality, a variant of omphalomesenteric duct, was observed in the umbilical cord 1 cm from the entry point into the abdominal wall, which itself was as an isolated mass of well-formed intestinal tissue free of structural defects. This intestinal tissue seems to be the remnant of an intestinal loop from caudal limb of midgut following physiological herniation during the third month of gestation.
