Dark Horizontal line across center of chest:

[TheStig]

(Picture included)   Hello, I just joined here.   (I’m 18 years old, male.)   For about two years I had a horizontal line across the center of my chest, sometimes it's dark and sometimes not.   I never really paid much attention to it until recently, because it seems to be darker than usual.

Here is a picture: http://img25.imageshack.us/img25/8117/darkline.jpg

I’m not sure why I have this, or what it could be caused by.   (I think I might be allergic to mold, but haven’t been to a doctor to verify this.)

I’m posting on this forum just to get another opinion on it, and maybe find out what it could be.      

Any help would be greatly appreciated.

Warm Regards, Dave

By the way, I meant to say the line is below my chest.
