Approximately 80% of infants are born with some kind of birthmark. Birthmarks come in a wide range of shapes, sizes, and colors, and they can show up anywhere on the body. Here are a few of the most common:
1- Stork Bites/Angel Kisses- This common birth mark occurs in about one third of all newborns. They are caused by a dilation of certain blood vessels and may become darker when the child cries or the temperature changes. The marks on the back of the neck are called stork bites and the ones on the forehead or eyelid are called angel kisses.
2- Port Wine Stains- are birthmarks that look like someone spilled wine on the skin. A port wine stain happens when chemical signals in tiny blood vessels don't "turn off," and those blood vessels get bigger. The extra blood turns the skin red. The mark grows as the child grows and eventually turns deep red or purple
3- Hemangioma are growths composed of blood vessels. affect about 2 to 5 percent of babies and are more common in girls, preemies, and twins.
4- Café au lait spots are common birthmarks that are flat and brown. Between 20 and 50 percent of newborns have one or two of these pigmented birthmarks.
