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.
Sometimes called a strawberry mark, 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.
