 Health Guide Drug Guide Images HemangiomaDefinitionA hemangioma is an abnormal buildup of blood vessels in the skin or internal organs. Alternative NamesCavernous hemangioma; Strawberry nevus CausesAbout 30% of hemangiomas are present at birth. The rest appear in the first several months of life. The hemangioma may be:
Symptoms
Most hemangiomas are on the face and neck. Exams and TestsHemangiomas are diagnosed by a physical examination. In the case of deep or mixed lesions, a CT or MRI scan may be performed. Occasionally, a hemangioma may occur with other rare conditions. Additional tests may be done for these syndromes. TreatmentSuperficial 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. Cavernous hemangiomas that involve the eyelid and block vision are generally treated with steroid injections or laser treatments. These quickly reduce the size of the lesions, allowing vision to develop normally. Large cavernous hemangiomas or mixed hemangiomas may be treated with oral steroids and injections of steroids directly into the hemangioma. Recently, lasers have been used to reduce the size of the hemangiomas. Lasers that emit yellow light damage the vessels in the hemangioma without damaging the skin over it. Some physicians use a combination of steroid injection and laser therapy. Outlook (Prognosis)Small, superficial hemangiomas often disappear on their own. About 50% go away by age 5, and 90% are gone by age 9. Possible Complications
When to Contact a Medical ProfessionalAll birthmarks, including hemangiomas, should be evaluated by the health care provider during a routine examination. Hemangiomas of the eyelid may interfere with the development of normal vision and must be treated in the first few months of life. Hemangiomas that interfere with breathing, feeding, or other vital functions should also be treated early. PreventionThere is no known way to prevent hemangiomas.
