Many babies have what are called “birthmarks” when they’re born or within the first few weeks of life. They can be brown, tan, blue, pink, or red. More than one in ten babies have (red) vascular birthmarks. These are made up of an increased number of blood vessels in the skin. They can be flat or raised, pink, red or bluish in color.
What Causes Birthmarks?
The exact causes of birthmarks are unknown. However, vascular birthmarks are not inherited, nor are they caused by anything that happens to the mother during pregnancy.
What Are the Different Types of Vascular Birthmarks?
There are different kinds of vascular birthmarks. Sometimes, the birthmark must be watched for several weeks or months before the specific type can be identified. The most common types of vascular birthmarks are macular (flat) stains, hemangiomas, and port wine stains. There are also some very rare types of vascular birthmarks.
The most common type of vascular birthmark that your physician may identify is called a macular stain. They are also called “angel’s kisses,” when they are located on the forehead, eyelids, tip of nose, or upper lip. When they are found on the back of the neck, they are frequently called “stork bites.” Macular stains are faint, mild red or pink, and flat. Angel’s kisses almost always go away by two years of age, but stork bites usually persist into adulthood.
