BIRTHMARKS (Nevi) Blue-Inexperienced or Blue-Grey Patch;
Mongolian Spot The Mongolian spot is a bluish splash like an ink stain with irregular borders that fade steadily into the encircling pores and skin. The mark was dubbed Mongolian as a result of it was first seen on Oriental infants. Really, any child with the tiniest diploma of pigmentation in his ancestry can have Mongolian spots.

Bruises rapidly change to a greenish-yellow coloration and vanish in just a few weeks. The Mongolian spot, alternatively, often lasts a yr or two. Maybe its solely significance is that it supplies seen proof of the pig-mented heritage all of us share.
