ABSTRACT: Ninety‐two Chinese Canadian newborn infants (49 boys and 43 girls J and 1633 Chinese Canadian children (819 boys and 814 girls J in Calgary, Alberta, Canada were examined for the presence of Mongolian spots. Mongolian spots were present in all newborns and disappeared slowly until 6 years of age when the rate of disappearance increased. At 10 years of age, none were found. The overall incidence regardless of age was 58% in boys and 53.3% in girls. The most frequent site of involvement was the sacrococcygeal area, followed by the gluteal and lumbar areas. Both sides were equally affected. In only 7.8% of boys and 3.3% of girls was the involved area greater than 15% of the body surface area. Most (63.8% of boys and 67.4% of girls J had less than 5% involved. The color of the Mongolian spots varied from gray to grayish blue to grayish black. In general, younger children had darker Mongolian spots.
