Definition of Hemangioma

A hemangioma is an abnormal buildup of blood vessels in the skin or internal organs.

Causes, incidence, and risk factors

About 30% of hemangiomas are present at birth. The rest appear in the first several months of life.

Signs and tests

Hemangiomas are diagnosed by a physical examination. In the case of deep or mixed lesions, a or scan may be performed.


Superficial or “strawberry” hemangiomas often are not treated. When they are allowed to disappear on their own, the result is usually normal-appearing skin. In some cases, a laser may be used to remove the small vessels.

Expectations (prognosis)

Small, superficial hemangiomas often disappear on their own. About 50% go away by age 5, and 90% are gone by age 9.
