Hemangioma is a common benign tumor that develops at the expense of blood vessel cells. Excessive proliferation of these cells form small supernumerary blood vessels where the mass appears reddish if the hemangioma is superficial, and more bluish in deep hemangioma, appearing on the skin. Hemangiomas are not present at birth and usually appear in the first days of life and grow for several months before stabilizing and then gradually disappearing. Usually isolated, they are mainly located on the head and neck, but can also be found on the rest of the body. Their color usually diminishes with age but if disfigurement is too great, they can sometimes be surgically removed.
