The green triangle indicates the so-called ‘hot spot’ of Mongolian spots. Most common spots appear in this area. Some other spots may appear in other regions such as the shoulders, upper back, arms, wrists, legs, ankles, lateral abdomen and elsewhere.

All spots are observed in the same 2-year-old normal Japanese female infant.
