So sorry, but there are not currently dermatologists here to answer questions, and we don't look at images- that's an incredibly inaccurate way to assist someone with a medical condition, which is why images can't be posted on the forums. HPV wouldn't cause your skin to turn brown, symptoms (if you experienced some) would be warts and itching. If you were exposed to it though, you should get tested- many times HPV will not display any symptoms.
