Music Trivia: What disease did Michael Jackson say caused him to turn black to white?

Michael Jackson was famous for his changing physical appearance:

The only thing that didn't change on Jackson's body during his life was his...umm...okay, I got nothing.  Nonetheless, Jackson's most famous physical transformation was likely his skin color.  Starting in the mid 1980s, Jackson's skin started becoming more noticeably pale - by the 90s, he was completely white.  Jackson adamantly denied allegations of skin bleaching; instead, he blamed his transformation on a particular disease.  So, off of Pocket Trivia: Music Trivia - What disease did Michael Jackson say caused him to turn from black to white?  Was it Vitiligo, Skin Cancer, Lupus or COPD?

Jackson did, in fact, have Lupus, but it is the Vitiligo that he says caused him to turn white.  In an interview with Oprah Winfrey in 1993, Jackson said that he had vitiligo, a disease which causes patches of skin to turn lose their pigmentation.  The disease, combined with Jackson's use of makeup to even out his complexion, caused him to appear white.  Jacson did, in fact, have the disease - this was confirmed in his 2009 autopsy.
