Overview
A hemangioma is an abnormal build up of blood vessels in the skin or internal organs.[1] It is also described as a congenital benign skin lesion consisting of dense, usually elevated masses of dilated blood vessels".[2] In most cases, hemangiomas will disappear over time. They are formed either during gestation or appear during the first few weeks of life and may present as a birthmark. Hemangiomas can be vivid superficial lesions, known as capillary hemangiomas (often referred to as "Strawberry Marks"), or they can be deep bluish swelling, known as cavernous hemangiomas. Sometimes they can be both superficial and deep. Approximately eighty percent are located on the face and neck, with the next most prevalent location being the liver. Although hemangiomas are benign, some serious complications can occur.
Historical Perspective
Hemangioma was first described by Dr. Robert Liston, a British surgeon, in 1843.[3]
Classification
Hemangioma may be classified according to International Society for the Study of Vascular Anomalies into six subtypes: infantile hemangioma, congenital hemangioma, tufted angioma, spindle-cell hemangioma, epithelioid hemangioma, and lobular capillary hemangioma.[4][5]
