Birthmarks are coloured marks on the skin that are present at birth or that develop shortly after birth. They may be brown, tan, black, blue or blue-grey, pink, white, red, or purple. Some birthmarks appear on the surface of the skin, some are raised above the surface of the skin, and some are located under the skin.
