A hemangioma is a benign growth of blood vessels, mostly congenital or developing in the first weeks of life. Capillary and cavernous hemangioma are distinguished. The capillary hemangioma is formed by capillaries of a small internal diameter, most often inside the skin or mucous membrane. Cavernous hemangiomas in contrast show vessels of a large diameter and are mostly red or blue. There are also cutaneous and subcutaneous hemangiomas as well as mixed forms. The cutaneous hemangioma is a sharply formed, flat or eminent knot. Most often it diminishes spontaneously after 2 to 5 years. In the case of the subcutaneous hemangioma, a blurred, blue and flat tumour is visible through the skin. A spontaneous regression is less frequent than in the case of the cutaneous form. Several hemangiomas on a body site are called hemangiomatose. They occur most often in combination with genetic diseases such as blue rubber bleb nevus syndrome, Hippel-Lindau syndrome, mafucci syndrome or sturge-weber-krabbe syndrome. Almost 10 % of all children have hemangioma, while 90 per cent of the hemangiomas are congenital or develop within the first months of life. After a short period of time, they stop growing. In general, 90 per cent of all hemangiomas diminish within the first 10 years of life completely or partially on their own. Hemangiomas are possible on all the areas of the body where there are blood vessels.
