Birthmarks

There are birthmarks and other pigmentation disorders that affect many people. Some of the most common abnormalities are listed here.

Birthmarks

This type of abnormal skin coloration will appear at birth, or in a few weeks following birth. It is important to remember that most birthmarks are non-cancerous, though a physician should examine your child if he or she is born with abnormally colored skin - or develops birthmarks shortly after birth. Certain birthmarks described below can pose health risks.

Pigmented Birthmarks

The discoloration of the skin will appear smooth and flat. These spots are known by several names, including Mongolian spots -- bruised or bluish in color, typically appearing on buttocks; Caf-Au-Lait spots -- light brown; and typical Moles, which are also called nevi. Moles should be monitored for bleeding, color, shape or size changes, or itching.

Macular Stains

These appear anywhere on the body as mild red marks, but they are not elevated. Macular stains are the most common type of vascular (from blood vessels) birthmark. These marks can come in two forms:

• "Angel''s kisses" may appear on the forehead and eyelids, but will typically disappear after age 2.
• "Stork bites" will appear on the back of the neck and can last into adult years.

Because these marks are often mild, treatment is not necessary.
