......A Mongolian Spot, Mongolian Fleck or Mongolian Blue Spot is a http://en.wikipedia.org/wiki/Benign - benign flat http://en.wikipedia.org/wiki/Congenital_disorder - congenital http://en.wikipedia.org/wiki/Birthmark - birthmark with wavy borders and irregular shape, most common among http://en.wikipedia.org/wiki/East_Asia - East Asians and http://en.wikipedia.org/wiki/Turkic_peoples - Turks , and named after http://en.wikipedia.org/wiki/Mongolians - Mongolians . It is also extremely prevalent among http://en.wikipedia.org/wiki/East_Africa - East Africans and http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas - Native Americans . ^{http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-tokyo-0 - [1] http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-skin-1 - [2]} It normally disappears three to five years after birth and almost always by http://en.wikipedia.org/wiki/Puberty - puberty . ^{http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-2 - [3]} The most common color is blue, although they can be blue-gray, blue-black or even deep brown......

Mongolian spots are most prevalent among http://en.wikipedia.org/wiki/Mongols - Mongols , http://en.wikipedia.org/wiki/Turkic_people - Turks , and other http://en.wikipedia.org/wiki/Asian_people - Asian groups, such as the http://en.wikipedia.org/wiki/Chinese_people - Chinese , http://en.wikipedia.org/wiki/Koreans - Koreans and http://en.wikipedia.org/wiki/Japanese_people - Japanese . Nearly all http://en.wikipedia.org/wiki/East_Asian - East Asian infants are born with one or more Mongolian spots. The incidence of Mongolian spot among East Asian infants is 90-95%. ^{http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-tokyo-0 - [1]} It is also common if only one of the parents is East Asian.

Among http://en.wikipedia.org/wiki/East_Africa - East African infants it is found at rates between 90-95%, and 85-90% of http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas - Native American infants. ^{http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-tokyo-0 - [1]}

The incidence among Caucasians, that is, the indigenous peoples of http://en.wikipedia.org/wiki/Europe - Europe , the http://en.wikipedia.org/wiki/Middle_East - Middle East , http://en.wikipedia.org/wiki/North_Africa - North Africa and the http://en.wikipedia.org/wiki/Indian_subcontinent - Indian subcontinent (Pakistan, India, Bangladesh, Sri Lanka) is between 1-10%. ^{http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-tokyo-0 - [1]} However, it has been found to be prominent among Europeans that have had extensive interaction with http://en.wikipedia.org/wiki/Hun - Hun cultures, most notably http://en.wikipedia.org/wiki/Hungarians - Hungarians who have a 22.6% occurrence rate among their population.^{[ http://en.wikipedia.org/wiki/Wikipedia:Citation_needed - citation needed ]}

Additionally, there is an incidence of 50-70% among some countries of the http://en.wikipedia.org/wiki/Americas - Americas , ^{http://en.wikipedia.org/wiki/Mongolian_spot#cite_note-tokyo-0 - [1]} presumably as a result of the http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas - Native American admixture found in http://en.wikipedia.org/wiki/Mestizo - mestizos (people of mixed http://en.wikipedia.org/wiki/European_ethnic_groups - European and http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas - Native American ancestry) that is an important racial group among some countries.......

I guess my questions would be;

         1.  Does anyone have different opinion about this compare to what is said in Wiki?

         2.  Did you have a Mongolian Spot, or in your family, or in your region?  

         3.  If yes to #2, then tell me more about the ethnic make up of yourself, family 

              or the region that you have seen this.

         4.  Can we read more into the genetic make up of the Mongolians, East Asians, Turks,

              Huns, East Africans, Native Americans, Eastern Europeans, with this, especially

              in comparison to Indians, Persians, and Caucasians who has very low incidents.

         5.  Is there any cultural symbolism to whether having or not having the spot,

              or for the size, location, color, etc since birth marks often symbolize certain 

              cultural connotations in old cultures. 

 

I guess that's enough questions for now.  I don't have any hidden agenda or trying to prove any theory.   I just find it interesting have some genuine questions.  If you have any interesting articles or websites I would appreciate them.  But I would really appreciate your personal accounts also.  I should have asked my parents if I had it or they know anything it at all.    

 

I've also read that here in U.S. some parents get accused of child abuse because they look similar to bruises, which any pediatrician should be able to tell the difference by just looking at it but most of the public is not even aware of such thing exist.
