hemangioma

noun    (Concise Encyclopedia)

Congenital benign tumour made of blood vessels in the skin. Capillary hemangioma (nevus flammeus, port-wine stain), an abnormal mass of capillaries on the head, neck, or face, is pink to dark bluish-red and even with the skin. Size and shape vary. It becomes less noticeable or disappears with age. Immature hemangioma (hemangioma simplex, strawberry mark), a reddish nub of dilated small blood vessels, enlarges in the first six months and may become ulcerated but usually recedes after the first year. Cavernous hemangioma, a rare, red-blue, raised mass of larger blood vessels, can occur in skin or in mucous membranes, the brain, or the viscera. Fully developed at birth, it is rarely malignant. Hemangiomas can often be removed by cosmetic surgery.
