A branchial cleft cyst is a type of cyst that is considered a type of birth defect. It is because the lump develops on one or both sides below the collarbone or neck of a child.

Symptoms of branchial cleft cyst include:
- Skin tag or lump on your child’s neck, upper shoulder, or slightly below their collarbone
- Neck swelling or tenderness
- Upper respiratory infection
