Introduction
In the early stage of vitiligo, depigmented patches typically appear in localized areas of the body or follow a dermatomal distribution. Spontaneous repigmentation is rare at this stage. Additionally, the number of patches is usually limited—most patients present with only one or two lesions. Vitiligo can occur on any part of the body; however, it most commonly affects the face, neck, waistline (belt area), dorsum of the fingers and toes, or areas subjected to chronic pressure from clothing, such as the bra strap or button sites in women.
Some individuals develop vitiligo in daily life—a challenging and persistent condition. Vitiligo typically presents with distinct clinical features. What are these characteristic symptoms? Details are outlined below:
① Number of Lesions
In the early stages of vitiligo, depigmented patches (leukoderma) usually appear locally—either on isolated areas of the body or along dermatomes. Spontaneous repigmentation is rare at this stage. Typically, only one or two patches are present initially. However, as the disease progresses, the number of patches increases progressively, potentially spreading diffusely across the entire body.
② Anatomical Distribution
Vitiligo can occur on any part of the body, but it most commonly affects sun-exposed or friction-prone areas—such as the face, neck, waistline (where belts rest), dorsa of fingers and toes, or sites subjected to chronic pressure from clothing (e.g., bra straps or button closures in women). It may also involve perianal or genital regions in women. These exposed areas are particularly susceptible to ultraviolet radiation; excessive sun exposure accelerates melanocyte depletion, thereby triggering or exacerbating depigmentation.
③ Skin Appearance
The skin affected by vitiligo differs from normal skin. Early lesions often feature a slightly raised, inflammatory, dusky-red border that may persist for several weeks—serving as an early warning sign of vitiligo onset.
