But the thing is, at the time when he started to develop it, her was the world's biggest superstar. I think you underestimate his power and influence at the time he started developing symptoms. If he had owned his condition and rocked it, I don't think it would have hurt his music sales one iota. Hell, twenty years later, he was accused of pedophilia, and even that didn't destroy his ability to make hit records. A weird looking skin condition in the 80's wouldn't even have made a blip.
