An umbilical polyp is a congenital condition; specifically, a congenital lesion resulting from an intestinal mucosal remnant at the umbilicus [1].
In simpler terms, it's a small growth or lump of tissue that's present at birth in the belly button (umbilicus). This growth is made up of leftover tissue from the baby's intestines that didn't fully disappear during development. Other umbilical anomalies include umbilical sinus, umbilical mucosal polyp, and cysts within a persistent fibrous cord [1].
