Vitiligo is leukoplakia, but leukoplakia is not necessarily vitiligo. At the early stage of vitiligo, the discoloration of leukoplakia is light, and the boundary with the surrounding normal skin is blurred. If this happens to people with white skin, it is often difficult to make a diagnosis in time. Carefully observe whether the surface of the white spot is smooth and dandruff-free, and whether the white spot is pale or milky white. If the boundary is blurred or spreads to normal skin, it may be vitiligo. Vitiligo often shows the following symptoms: 65438+. 2. The number of depigmented spots is small, generally only 1-2, and most of them appear on bare skin. 3. Except for depigmentation, the depigmented skin is the same as the surrounding skin, without itching, desquamation, atrophy and other changes. 4. In the absence of other skin diseases, early vitiligo should be considered first.
