Birthmarks - Topic Overview

SYMPTOMS & TREATMENTS

What are birthmarks?

A birthmark is a colored mark on or under a newborn baby’s skin. Some birthmarks show up soon after a baby is born. Most birthmarks are obvious at birth. Some kinds of birthmarks fade or go away as a child gets older. Others stay the same or get bigger, darker, or thicker.

There are many kinds of birthmarks. They can be any size or shape and can be different colors, such as blue or blue-gray, brown, tan, black, pink, white, red, or purple. Some birthmarks are smooth, and some are raised.

Nearly all birthmarks are harmless and painless. But it’s important to have a doctor check all birthmarks, just to be sure they are okay.

What causes birthmarks?

Some birthmarks are from extra color (pigment) in the skin. Other birthmarks are blood vessels that are bunched together or do not grow normally.

It is not clear why some children have birthmarks and others do not.

What kinds of birthmarks are there?

  • Salmon patches (also called stork bites, angel kisses, and macular stains). Salmon patches are thin, flat, light pink or red birthmarks. They tend to be on the back of the neck, the upper eyelids, upper lip, or between the eyebrows.
  • Congenital moles (nevi). Congenital moles can grow anywhere on the body. They vary in size and shape. Most are brown.
  • Café-au-lait spots. Most café-au-lait spots are smooth, oval birthmarks. They range in color from light brown to chocolate brown and usually are found on the torso, buttocks, and legs.
  • Mongolian spots. Mongolian spots are smooth, blue or blue-gray birthmarks. They are often uneven in shape and are on the lower back and buttocks.
  • Hemangiomas. Hemangiomas are raised birthmarks. They are blue, red, or purple. They are clumps of blood vessels that did not grow normally. Hemangiomas grow in many shapes and sizes and can grow on the skin or deeper in the body.
  • Port-wine stains. Port-wine stains are birthmarks that are pink-red at birth and then become a darker red-purple. Port-wine stains are blood vessels that did not grow normally. They can be small, or they can cover a large area of the body.

Do birthmarks need to be treated?

Most birthmarks are harmless and need no treatment. Some will even fade or disappear over time. Some kinds of birthmarks can be removed with surgery or lightened with a laser. But these treatments can hurt, and they may not work. That is why most birthmarks are not treated.

Only rarely does a birthmark need to be treated because it causes a medical problem. This can be a problem with sight, breathing, hearing, speech, or movement. And birthmarks that grow rapidly, such as severe infant hemangiomas, need to be treated right away. Also, birthmarks that grow on internal organs need treatment.

Even if your child’s birthmark bothers or worries you, try not to let your child know how you feel. Ask others not to make a big deal out of it. If a birthmark upsets your child, it may help to have your child talk with a trusted doctor. If your child is still upset, talking to a counselor or support group may be a good idea to help him or her feel better.

Is it important to have birthmarks checked?

Although most birthmarks are harmless, some are not. If you see a birthmark on your baby, make sure that a doctor has seen it. If a birthmark grows, bleeds, hurts, or gets infected, see a doctor to have it checked.
