I need a diagnosis...
Marc, I must say that I agree with both Shelia and Darlene. It does look like ringworm sort of. My kids used to get them and I would put a cup of clorox in a pint of water and dap that on it. Old folks used to do it and it would go away. On the other hand I must say that it also reminds me of a skin cancer that my friend had. I think that until you know what it is don't put anything on it!!! See the doctor.
