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
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 or lumpy.
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 don't grow normally.
It's not clear why some
children have birthmarks and others don't.
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 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 didn't grow normally. Hemangiomas grow in many shapes and sizes. They may
grow only on the skin, or they may extend deeper into the body.
Port-wine stains. Port-wine stains are birthmarks that are pink-red at birth and

There are several ways to fade, shrink, or remove birthmarks. These include:
Medicines, such as propranolol or corticosteroids.
Your options will depend on the type of birthmark, where it is, and what problems it's causing. Treating a birthmark can be a big decision. The treatments may not work, and they can be painful and cause side effects.
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
Is it important to have birthmarks checked?
If you see a
birthmark on your baby, make sure that a doctor has seen it. Although most birthmarks are harmless, some aren't.
If a birthmark
grows, bleeds, hurts, or gets infected, see a doctor to have it checked.
