What is an umbilical polyp?

An umbilical polyp is a firm, red or pink bump at the belly button (navel). It's visible after a newborn's umbilical stump dries up and falls off. The polyp is made of tissue found in the intestinal lining. It develops while the fetus is still forming in the uterus.

These polyps can look like another type of bump called an umbilical granuloma. But umbilical polyps are often bigger. They also require different treatment. They are also less common.

What causes it?

In normal fetal growth, certain tissues are reabsorbed by the body. An umbilical polyp happens when some or all of these tissues remain.

What are the symptoms?

Symptoms can include:

• A red or pink bump at the navel.
• Drainage from the bump.
• Lower belly (abdominal) pain.

How is it treated?

An umbilical polyp is usually treated with surgery. Other tests may also be done to make sure there aren't any problems with the infant's intestines.
