I just finished reading this article at Yahoo! about birthmarks.
I got curious when I saw the title since I have this light brown spot
that looks like a small scorpion at my back just below my right shoulder blade.
And after reading this article I learned that my birthmark is called café au lait spot.
( ´艸｀) What a cute name for a birthmark~
Anyway, there are varied birthmarks enumerated int he article such as the
Mongolian blue spots, moles, vasular birthmarks,
muscular stains, hemangiomas and port wine stains.
You'll learn more about these from the article
so try and give it a peek if you're interested with bithmarks
and the scientific explanations behind it.
