What causes rashes on the shaft of the penis?
Patient: My boyfriend appears to have a itchless, painless, petichial-type rash on the shaft of his penis for approx one week. There is no drainage noted from any of the sites and it appears to only be on the top of the shaft. He is uncircumcised and I believe he has erectile dysfunction, because he uses a band made of velcro to help maintain his erection. What could this rash be?
