[Intestinal polyp of the umbilical cord]

The morphology, pathogenesis, complications and differential diagnosis of an intestinal polyp of the umbilical cord are presented. The polyp were detected postnatal on the umbilical cord in an healthy male newborn. The presents of intestinal tissue upon the umbilical cord ist possible about the persistence from remnants of the ductus omphalomesentericus with prolapse and differentiation of the intestinal cells. The ductus omphalomesentericus is a tubular structure, a communication between the developing embryonic gut and the yolk sac, forming during the early embryonic life. Obliteration of the omphalomesenteric duct is usually complete by the 10(th) week of gestation. Various portions of the duct may persist, however, giving rise to polyps, fistulas or cysts of the umbilical cord with potentially dangerous clinical consequences. Other tumors of the umbilical cord are myxoma, angioma and teratoma are differential diagnosis.
