These polyps are rare abnormalities and are usually diagnosed in neonates, especially the congenital one, although lesions have been found in older children and also in adults, but in the latter they are exceptional, and it is usually neoplastic, and of course it is an acquired lesion, with a wide spectrum of different pathologies. Umbilical lesions are rare, but it is important to cautiously inspect and investigate every umbilical nodule or growth to rule out the possibility of embryological remnant and associated congenital anomaly in infants and children and hidden malignancy in adults. Part of Springer Nature. At surgery, an umbilical polyp was excised, the histology of which revealed columnar epithelium with villi formation suggesting small intestinal mucosa (fig. Vitello-intestinal duct anomalies are rare and occur in 1-2% of the population. Kaohsiung J Med Sci. It is a rare anomaly, resulting from persistence of all or part of the omphalomesenteric duct {OMD} or the urachus. Am J Surg Pathol. Fitz R. Persistent omphalomesenteric remains, their importance in the causation of intestinal duplication, cyst formation, and obstruction. Umbilical polyps are firm masses comprised of intestinal or urinary tract tissue. This service is more advanced with JavaScript available, Umbilicus and Umbilical Cord It will heal after treatment with antibiotics. In adults, metastases from intra-abdominal tumors need to be excluded. King Edward VIII Hospital, Department of General Surgery, Nelson R Mandela School of Medicine, University of Kwa-Zulu Natal, South Africa. The causes of umbilical hernia are congenital and acquired malformation, but an apparent third cause is really a cause of a different type, a paraumbilical hernia.. Congenital. 1947;54:10–36. Cite as. doi: Iwasaki M, Taira K, Kobayashi H, Saiga T. Umbilical cyst containing ectopic gastric mucosa originating from an omphalomesenteric duct remnant. Aim of the study: The umbilical polyp is a rare congenital lesion resulting from the persistence of omphalomesenteric duct (OMD) enteric mucosa at the umbilicus. Acta Chil Belg. 2008;11:165–6. Case Rep Med. Six patients … 1953;28(137):1–7. It is rare but possible for an adult to develop an umbilical granuloma. Patients should be consented for laparotomy; however, routine exploration of the peritoneal cavity is unnecessary.4, S. Cheddie, FCS(SA) 1884;88(175):30–57. Fibrous umbilical polyp: a distinct fasciitis-like proliferation of early childhood with a marked male predominance. There are usually no long-term issues. The most common umbilical anomaly is the umbilical polyp which is often lined by small-bowel mucosa and less commonly, pancreatic and gastric mucosa. Patent omphalomesenteric duct and its relation to diverticulum of Meckel. Actas Dermosifiliogr. {1} Usually umbilical polyp represents only the distal remnant of OMD or the urachus. They tend to be larger than granulomas, and do not respond to silver nitrate. Umbilical polyps which are covered with real epithelium poses a diagnostic challenge from clinical point of view.

An umbilical granuloma is a superficial abdominal wall problem. Umbilical polyps are generally regarded as innocuous but may be associated with other vitello-intestinal duct defects such as underlying sinus, cyst, fistula, or band. Nix and Young classified the vitello-intestinal duct anomalies into four major categories: complete patent VD (umbilical enteric fistula); partially patent VD including peripheral portion (umbilical sinus), intermediate portion (vitelline cyst), and enteric portion (Meckel's diverticulum); mucosal remnant at the umbilicus (umbilical polyp); and congenital band (obliterated VD)2 (fig. 1990;25:214–5. A case of small intestinal obstruction in an adult associated with persistent OMD has been reported.4 Cases of umbilical mucosal polyp similar to this case have been previously reported.6–8 In a series of 13 umbilical polyps studied, 11 showed small intestinal mucosa (one associated with pancreatic tissue and one with gastric mucosa), and two showed colonic mucosa.
