Babies with birthmarks should be examined and diagnosed by your child's physician. Some of the common variations in skin color and birthmarks are described below. These are small pink or red patches often found on a baby s eyelids, between the eyes, upper lip, and back of the neck. They are caused by a concentration of immature blood vessels and may be the most visible when the baby is crying. Most of these fade and disappear completely.
Mongolian spots are blue or purple-colored splotches on the baby s lower back and buttocks.
The spots are caused by a concentration of pigmented cells. They usually disappear in the first four years of life. This is a bright or dark red, raised or swollen, bumpy area that looks like a strawberry. Hemangiomas are formed by a concentration of tiny, immature blood vessels. Most of these occur on the head.
