How to Determine if White Spots Are Vitiligo

To determine whether white patches are白癜风 (vitiligo), the following aspects can be considered: 1. **Observe the color**: The white patches of vitiligo are often milky white or light pink in color, with a smooth surface and no rash. As the condition progresses, the patches may become even whiter. 2. **Check for scaling**: The surface of vitiligo patches is smooth, without scaling or crusting, which differentiates it from other skin conditions that may also present with white patches but include scaling. 3. **Observe the borders**: Vitiligo patches typically have clear boundaries separating them from normal skin, with increased pigmentation at the edges. During the progressive stage, the edges may appear blurred, but they tend to become more distinct during the stable stage. 4. **Note the shape**: Vitiligo patches are commonly round, oval, or irregularly shaped, varying in size from as small as a fingernail to much larger areas. If the above features are present, it is advisable to seek medical attention promptly for further examination and diagnosis by a qualified physician.
