Congenital Umbilical Appendix Misdiagnosed as Umbilical Granuloma: Report of 2 Cases

摘要

Background: Umbilical cord hernia is an uncommon umbilical anomaly which develops during 10th to 12th weeks of gestational age owing to failure of complete bowel return into coelomic cavity. In extremely rare cases appendix is the only trapped organ in hernia sac which may erode the overlying membrane and simulate umbili-cal granuloma. Case Report: Two infants presented with delayed umbilical cord separation with a reddish mass at umbilicus which was initially diagnosed as umbilical granuloma. Surgical exploration on failure of conservative measures revealed it as vermiform appendix. Appendectomy was done in both cases. Conclusion: Vermiform appendix at umbilicus is a rare congenital anomaly and may simulate other pathologies at umbilicus.
