Venous malformations are caused by abnormally formed, dilated veins. Although present at birth, they may not become apparent until later in childhood or adulthood. Venous malformations appear in 1% to 4% of babies. They are often found on the jaw, cheek, tongue, and lips. They may also appear on other areas of the body. They will continue to grow slowly, and they don't shrink with time. Treatment - often sclerotherapy or surgery -- may be necessary for pain or impaired function.
