A hemangioma may be present at birth, but more often appears during the first several months of life. It starts out as a flat red mark anywhere on the body, most often on the face, scalp, chest or back. Usually a child has only one mark, but some children may have more than one, particularly if they're part of a multiple birth.
During your child's first year, the red mark grows rapidly and becomes a spongy mass that protrudes from the skin. The hemangioma then enters a rest phase and, eventually, it begins to slowly disappear.
Half of all hemangiomas resolve by age 5, and nearly all hemangiomas are resolved by age 10. Although the color of the birthmark also fades, faint — but permanent — discoloration of the skin or residual extra skin may remain.
When to see a doctor
Your child's doctor will monitor the hemangioma during routine checkups. Contact your child's doctor if the hemangioma bleeds, forms a sore or appears infected.
