A hemangioma — once known as a strawberry hemangioma — is a birthmark that appears as a bright red patch or a nodule of extra blood vessels in the skin. About 30 percent of hemangiomas are present at birth and are typically found on the face or neck.

It grows during the first year of life, and then recedes over time. A hemangioma is usually benign and isn't associated with other medical conditions.

Most hemangiomas require no treatment. When they are allowed to disappear on their own, the result is usually normal appearing skin typically by age 10. In some cases, a laser may be used to remove the small vessels.

A health care provider should evaluate all birthmarks, including hemangiomas, during a routine examination. There is no known way to prevent a hemangioma.
