Skin angiomas are mostly benign neoformations due to the abnormal cellular development of sanguneous or lymphatic vessels. The most common form of cutaneous angioma is hemangioma, which consists of a proliferation of blood vessels and usually appears at birth or during the first year of life, then recedes spontaneously over time, requiring no treatment. Much rarer is lymphangioma, which affects lymphatic vessels and can be capillary or cystic in nature.
