More common in Asian children than Caucasian children

Mongolian spots are congenital gray blue macular lesions, characteristically located on the lumbosacral area, although they can occur anywhere on the skin. They are almost always (99–100%) in infants of Asiatic or Amerindian origin, although reports in Black, and rarely, White infants have occurred. They usually disappear in early childhood, and generally the lesions are solitary.
