Will the Depigmented Patches Spread?

There is no way to predict if vitiligo will spread. For some people, the depigmented patches do not spread. The disorder is usually progressive, however, and over time the white patches will spread to other areas of the body. For some people, vitiligo spreads slowly, over many years. For other people,spreading occurs rapidly. Some people have reported additional depigmentation following periods of physical or emotional stress.
