Hemangiomas are very common in babies, usually noticed within the first few weeks of life. They tend to occur more often in girls, appearing anywhere on the body (more than half are on the head and neck region) in as many as one out of every 20 to 25 babies. Typically, hemangiomas represent clusters of blood vessels generally close to the surface of the skin that are raised and red or purplish in color. Others can begin in the deeper layers of the skin. Hemangiomas do tend to get larger during the first year of life and then begin to shrink (involute) over the next few years. A hemangioma's color usually has disappeared by five to seven years of age.

Although hemangiomas can be cosmetically worrisome to parents, concern should initially revolve around whether they are quite large or whether their size and location are causing secondary effects. For example, some children have had them very near their windpipe, resulting in breathing difficulty. Of course, these would warrant immediate attention. Sometimes hemangiomas can be associated with, or located near, other malformations.

Be reassured that most hemangiomas, like the one you described, do not require evaluation by a specialist who deals with these types of vascular growths. They can more easily be observed by your child's pediatrician and referral made if the diagnosis is in question, if the hemangiomas are medically problematic, or if you are in need of further reassurance.
