This is a very common pigmentary disorder that affects most Asian babies. It occurs less commonly in Caucasian babies. It appears as greenish pigmentation usually on the back and buttocks. The pigmentation normally lightens as the child grows up. However, in some cases, the pigmentation may persist into adulthood. Mongolian spots can be lightened by the use of a laser. The laser therapy is safe and well- tolerated. Again, many sessions may be required to give good cosmetic outcome.
