Birthmarks: A birthmark is a benign irregularity on the skin which is present at birth or appears shortly after birth, usually in the first month. They can occur anywhere on the skin. Birthmarks are caused by overgrowth of blood vessels, pigment cells, smooth muscle, fat, skin cells, and other tissue. Some pigmented birthmarks carry a small risk of malignant transformation with time.
