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), dorsa of fingers and toes, or areas subjected to chronic pressure from clothing, such as bra straps or button sites in women.
Some individuals develop vitiligo in daily life—a challenging and persistent condition. Vitiligo typically presents with distinct clinical manifestations. 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 specific dermatomes. 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; however, it most frequently occurs on exposed or friction-prone areas—including the face, neck, waistline (where belts rest), dorsa of fingers and toes, or sites subjected to pressure from bra straps or buttons in women. It may also involve the perianal region or female genitalia. These exposed areas are particularly susceptible to ultraviolet radiation; excessive sun exposure accelerates melanocyte depletion, thereby triggering depigmentation. During active disease progression, lesions often expand outward into adjacent normal-appearing skin, resulting in new patches at the periphery.
③ Skin Changes
The skin affected by vitiligo differs from normal skin. Early vitiligo lesions are often preceded by a slightly raised, inflammatory, dusky-red border that may persist for several weeks—serving as an early warning sign of the condition.
