Abstract:
A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.
