Hello, i have a light brown round patch size of a quarter approximately on the inside of my upper thigh. I have had this for about a year, no itching, no bumps, just a discoloration. I have shaved, washed, etc directly on it and no spreading has occurred. I do not think it is ringworm due to no symptoms besides the discoloration on my skin.
Maybe you'll know what it is...
Thank you!
