Mongolian spots are benign, congenital blue-gray macules or patches commonly found in Asian, black, and Hispanic infants (and in 5% of white infants). They are most often located in the sacrogluteal area and the upper back. The lesions may be solitary or multiple, vary in color intensity, and frequently enlarge until about age 2, when they gradually fade and disappear. Approximately 5% persist into adulthood.
