How is the long white spot on the hand?

The basic manifestation of vitiligo is white plaque, but the severity of depigmentation can be different. According to the severity of the disease, pale white, milky white, cloudy white and china white may appear in turn. Vitiligo leukoplakia can appear alone or in patches. With the development of the disease, it gradually spreads, and adjacent white spots will gradually merge into pieces. After a certain degree, the white spot will be stable and will not change.

2. Skin diagnosis

Generally speaking, the boundary between vitiligo leukoplakia and normal skin is obvious, and the edge of leukoplakia can be blurred in the early stage. Sometimes there will be a diffusion halo around leukoplakia, and the color is between normal skin and leukoplakia. There are three kinds of hair in vitiligo and leukoplakia: white, normal color and black and white. After the white spots disappear, the hair can gradually become normal color.
