A cystic hygroma is a rare type of cyst that babies can get, usually in their head or neck, if their lymphatic system gets blocked while it’s growing. (This system helps filter out harmful things, including germs.) Doctors often find cystic hygromas before a baby is born.
Only one in 8,000 babies is born with this kind of cyst. Some of them may also have certain birth defects. So, if your baby has a cystic hygroma, your doctor will probably suggest tests to check for other problems. But some babies born with a cystic hygroma are healthy.
Sometimes these cysts go away on their own. If not, it’s important to get surgery to remove a cystic hygroma so it doesn’t harm nearby areas of the body, become infected, or make your baby uncomfortable as they grow.
Symptoms of a cystic hygroma depend on where and how big it is. The growth may make it hard for nearby organs and other body parts to work the way they should.
In newborn babies, a cystic hygroma looks like a bulge under the skin, which may be slightly blue. Babies born with this type of cyst often have a hard time eating and may grow more slowly than those without cystic hygromas. If a cystic hygroma is near the throat, your baby may have trouble breathing. These cysts can become infected.
