A hemangioma (he-man-jee-O-muh) is a birthmark that most commonly appears as a rubbery, bright red nodule of extra blood vessels in the skin.
A hemangioma grows during the first year of life, and then recedes over time. A child who had a hemangioma during infancy usually has little visible trace of the growth by age 10.
A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back. Treatment of a hemangioma usually isn’t needed, unless the nodule interferes with vision or breathing.
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. 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.
About 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 looks infected.
Seek medical care if the condition interferes with your child’s vision, breathing, hearing or elimination.
A hemangioma consists of an abnormally dense group of extra blood vessels. It’s not clear what causes the blood vessels to group together, although there may be a hereditary component involved.
Hemangiomas occur more often in:
Occasionally, a hemangioma can break down and develop a sore. This can lead to pain, bleeding, scarring or infection. Depending on where the hemangioma is situated, it may interfere with your child’s vision, breathing, hearing or elimination, but this is rare.
There are many causes of split earlobes and widened ear piercing holes. Split earlobes are often caused by trauma, which may occur if earrings are pulled through the piercing hole. Additionally, wearing earrings — especially heavy earrings — can lengthen the piercing hole and eventually pull through over time. People with thin earlobes are predisposed to this occurring.
