A. Mongolian spots are flat blue or gray birthmarks on a newborn's body. Although most commonly located on a baby's lower back and buttocks, they can also occur on other areas of their body.
Although they can look like bruises, they are normal and not a sign of child abuse or any other condition. They often fade as a child gets older.
They are much more common in dark skinned races, especially African, Asian, East Indian, and Hispanics, but can also occur in up to about 9 percent of Caucasian children.
