title: Umbilical polyps.
abstract: We report three patients, ages 5 years, 3 years, and 4 days, with umbilical polyps. In the third child the polyp was associated with an umbilical enteric fistula. An umbilical polyp is the result of incomplete closure of the omphalomesenteric duct and becomes apparent after the umbilical cord is detached. It is a reddish tumor of a few millimeters; it seldom bleeds or is exudative. We consider it important to study every case in detail in order to exclude possible underlying embryologic anomalies such as Meckel's diverticulum and umbilical enteric fistula.
