Introduction
In the early stage of vitiligo, depigmented patches typically appear locally or in a dermatomal distribution. Spontaneous resolution of these patches is rare, and most patients present with only 1–2 lesions. Vitiligo can occur on any part of the body; however, it most commonly affects the face, waistband area, dorsum of fingers and toes, or areas subjected to pressure from bra straps or buttons in women. It may also appear around the anus or on the female genitalia.
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 or follow a dermatomal distribution. Spontaneous repigmentation is rare. Initially, only one or two patches are commonly observed. However, as the disease progresses, the number of patches increases progressively—potentially becoming widespread across the entire body.
② Anatomical Distribution
Vitiligo can affect any part of the body, but it most frequently occurs on exposed or friction-prone areas—including the face, neck, waistline (where belts rest), dorsum of fingers and toes, or sites subjected to pressure from bra straps or buttons in women. It may also appear around the anus or in the female genital area. These exposed regions are particularly susceptible to ultraviolet radiation; excessive sun exposure accelerates melanocyte depletion, thereby triggering depigmentation.
③ Skin Changes
The skin affected by vitiligo differs from normal skin. Early lesions often exhibit a slightly raised, inflammatory, dusky-red border that may persist for several weeks—serving as an early warning sign of vitiligo onset.
