What is an umbilical granuloma?
When your baby is born, their umbilical cord is clamped and cut. The small part of the umbilical cord that is still attached to your baby is called the ‘umbilical stump’ or ‘umbilical cord stump’.
Your baby’s belly button forms when their umbilical cord stump falls off several days after birth. Your baby’s belly button is also known as their ‘umbilicus’.
Sometimes, moist red tissue can form over the umbilical stump area. This can form a small lump and is called an ‘umbilical granuloma’.
Umbilical granulomas are common in babies.
What are the symptoms of an umbilical granuloma?
If your baby has an umbilical granuloma, you may notice some pink or red tissue at the base of their umbilical stump (where their cord stump fell off). The tissue is moist and soft.
An umbilical granuloma may ooze a small amount of clear or yellow fluid.
Umbilical granulomas are usually painless.

How is an umbilical granuloma diagnosed?
Your doctor will be able to diagnose an umbilical granuloma by examining your child. No tests are needed.
How is an umbilical granuloma treated?
Umbilical granulomas may slowly heal on their own if you keep your baby’s belly button clean and dry.
To help an umbilical granuloma to heal, your doctor may recommend salt treatment.
Salt treatment involves:
- Cleaning your baby’s belly button area with warm water and drying the area.
- Applying a small pinch of table or cooking salt to their umbilical granuloma.
- Covering the area with a dry gauze dressing for 30 minutes to keep the salt on.
- After 30 minutes, removing the salt using a cotton ball that has been soaked in warm water.
- Making sure the area is kept clean and dry.
This procedure can be done 2 times a day for 3 to 5 days. Keep your baby’s belly button clean and completely dry between salt treatments.
The granuloma should start to get smaller and dry out. The area should gradually heal. You may notice that it changes colour. If your baby’s umbilical granuloma doesn’t improve after salt treatment, see your doctor.
Do not try to pick the granuloma off.
Sometimes, topical treatment may be applied to the granuloma by your doctor. Surgery is sometimes recommended to remove an umbilical granuloma.
What are the complications of an umbilical granuloma?
If an umbilical granuloma (or the cord stump) becomes infected, your baby can become unwell. Signs of an infection can include:
- redness and warmth around the belly button area
- a bad smell coming from the belly button area
- fluid leaking from the area
- fever (a temperature above 38°C)
