Vitiligo

Vitiligo is a chronic disorder that causes depigmentation in patches of skin. It occurs when the melanocytes, the cells responsible for skin pigmentation which are derived from the neural crest, die or are unable to function. The precise pathogenesis, or cause, of vitiligo is complex and not yet fully understood. There is some evidence suggesting it is caused by a combination of autoimmune, genetic, and environmental factors. It is also common in people with thyroid disorders. The population incidence worldwide is considered to be less than 1 percent. Non-segmental vitiligo has a greater prevalence than the disorder's other form(s).
The most notable symptom of vitiligo is depigmentation of patches of skin that occurs on the extremities. Although patches are initially small, they often enlarge and change shape. When skin lesions occur, they are most prominent on the face, hands and wrists. Depigmentation is particularly noticeable around body orifices, such as the mouth, eyes, nostrils, genitalia and umbilicus. Some lesions have hyperpigmentation around the edges. In regards to psychological damage, vitiligo can have a significant effect on the mental health of a patient. Psychological stress may even result in an individual becoming more susceptible to vitiligo. Patients who are stigmatised for their condition may experience depression and similar mood disorders.

Michael Jackson was diagnosed in 1986 with vitiligo and lupus; the latter was potentially lethal but was in remission in Jackson's case. In a 90-minute interview with Oprah Winfrey in February 1993, Jackson dismissed suggestions that he bleached his skin, admitting for the first time that he had the illness. The admission went on to promote awareness of vitiligo, a relatively unknown condition before then. After his death, a friend claimed he started wearing his signature sequin glove to cover the vitiligo that had begun to appear.
