A strawberry hemangioma on an infant is a bright red nodule on the skin that is rubbery to the touch, Mayo Clinic says. A strawberry hemangioma occurs when an abnormally dense group of extra blood vessels forms. They usually grow during the first year of life, then gradually shrink and disappear by the age of 10, although they may leave behind extra skin or a permanent discoloration of the skin.
A strawberry hemangioma usually appears during an infant's first few months of life, but they can be present from birth, explains Mayo Clinic. It usually first appears on the scalp, back, face or chest as a flat red mark. This rapidly swells into a spongy red mass that protrudes from the skin. They are more common in premature infants, females and white infants.
Strawberry hemangiomas generally cause no serious issues and do not require any treatment, although they can occasionally interfere with breathing, vision, elimination of wastes or hearing, Mayo Clinic says. Occasionally a strawberry hemangioma breaks down and forms a sore, which causes a risk of infection, scarring, bleeding or pain. Treatments include laser surgery to stop growth or remove the hemangioma, and corticosteroid injections. A corticosteroid injection can cause side effects, including high blood pressure, cataracts, poor growth and high blood pressure.
