Vascular birthmarks in children.

Several different systems of terminology for vascular birthmarks are defined using descriptive terms (capillary hemangioma, cavernous hemangioma, mixed hemangiomas, etc.) for consistency. Capillary hemangiomas have the most complete and rapid rate of resolution whereas cavernous hemangiomas are considerably slower to respond. Vascular lesions in the V1 distribution of the trigeminal nerve and in the lumbosacral area need imaging studies for presence of internal involvement. Vascular lesions that require systemic therapy are those that obstruct vision, airway, or genitourinary tract; and produce congestive heart failure or consumption of formed blood products. The various modalities of treatment including steroids, are discussed briefly.
