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.
本文介绍了脐带肠息肉的形态学、发病机制、并发症及鉴别诊断。该息肉在一名健康男婴出生后于脐带上被发现。脐带上存在肠道组织可能是由于卵黄管遗迹持续存在，伴有肠道细胞脱垂和分化。卵黄管是一种管状结构，是发育中的胚胎肠道与卵黄囊之间的通道，在胚胎早期形成。卵黄管通常在妊娠第10周完全闭塞。然而，导管的各个部分可能会持续存在，从而导致脐带息肉、瘘管或囊肿，产生潜在的危险临床后果。脐带的其他肿瘤如黏液瘤、血管瘤和畸胎瘤需要进行鉴别诊断。
