It gets its name from port wine, a type of wine that is dark maroon. Kids who have port-wine stains usually have them on the face and neck. Doctors can sometimes use laser surgery to treat birthmarks so that they can't be seen as much. It's important to remember, though, that birthmarks really aren't a big deal and kids who have them aren't any different from kids who don't. If you have any raised brown, blue, or black spots on your skin, these aren't birthmarks.
Moles are tiny collections of pigment cells - cells that contain color.
Like birthmarks, moles don't hurt and usually aren't a sign of illness in kids. For specific medical advice, diagnoses, and treatment, consult your doctor.
