It is the most common cause of an umbilical mass in neonates. Parents will describe a persistent discharge from the umbilicus after the cord has dried and separated. It appears soft, pink, wet, and friable. Infants with an umbilical granuloma do not have localized swelling, redness, warmth, tenderness, or fever. An umbilical polyp is a rare anomaly resulting from the persistence of the omphalomesenteric duct or the urachus and may have a similar appearance. A polyp is usually firm with a mucoid secretion. The differential diagnosis also includes omphalitis, an infection of the umbilicus and surrounding structures, which should be considered in ill-appearing neonates.
