Hello Dr.
I have had ringworm as a child and remember what it looked like. I have noticed a spot on the head of my penis which looks pretty much the same. It is round/oval in shape, and raised along the edges/lines, with a sort of "clearing" in the center. I noticed this some months back, but it was smaller at the time, and I figured it was just some sort of irritation which would eventually go away.
It has not gone away, and has gotten slightly larger. I've tried using some micatin that I had at home, but it doesn't seem to be doing anything. Ive read some articles about penile cancer and it certainly isn't a lesion or bump. What could it be? How can I clear it? Does it pose any health issues?
