London, February 7: Pop star Michael Jackson's fans have been worrying about his health ever since the `Thriller' star was seen with a raw and painful-looking skin condition.
Jacko was seen coming out of a Beverly Hills clinic this week.
According to the Daily Express, the singer appeared with cracked, swollen hands and blotchy cheeks, before stepping into his car still wearing a surgical cap and mask.
He is believed to be undergoing treatment for Vitiligo, a disease which causes loss of pigment and irregular, patchy skin.
