I've had this for about a month now. Hasn't grown, hasn't spread. Only itches when I scratch it and irritate the skin. Red circle, so I thought it was ring worm, but no more anywhere else in the body. This is on my right breast. Middle of circle is skin color - whiteish color, very dry/thin skin inside circle. Other then that no other symptoms. No itching. No burning, not spreading. It's about the size of a nickel.
