An umbilical polyp is a small abnormal outgrowth of the omphalomesenteric - vitelline duct - mucosa that is retained in the umbilicus. It resembles an umbilical granuloma except that it does not disappear after cauterisation with silver nitrate. It may be associated with a persistent vitelline duct or an umbilical sinus.
Treatment is by excision of the mucosal remnant.
