Not all birthmarks are pale and flat. Hemangiomas are rubbery growths or bright red nodules that get their unusual appearance from the extra blood vessels at their site. Typically, this type of birthmark shows up in infancy and grows until the child is about one. Then the hemangioma begins to fade and shrink, usually fading completely by age ten.
1. How Do Hemangiomas Start?
While mature hemangiomas can be quite large and protrude considerably from the skin, they typically start out as a small flat mark on the face, chest, or back. They can also appear on the scalp and other places on the body. While some children have one, others may have several. Caucasian children most commonly develop hemangiomas, and those who are one of the multiple births often report multiple growths.
