Vitiligo Proof?!

Hi! So I haven't been on fanpop in over a year or more, but I still remember a lot of you guys and this site was really important to me a while back. I just rediscovered it and remembered my old username and everything and it brought back some great memories! So i'm back. :D

Anyways, this is random but I remember hearing something about how it stated on Michael's death certificate that he did in fact have vitiligo. I never had any doubt in the fact that he had a skin disease, but I was just curious and was reading his death certificate and couldn't find anything on it. Is there more to the death certificate than what was released to the public?
Anyone have thoughts on this?
thanks. :)
