Vitiligo

Vitiligo is a chronic skin condition characterized by the loss of pigmentation, leading to the development of white patches on the skin. This occurs due to the destruction or dysfunction of melanocytes, the cells responsible for producing the pigment melanin. The exact cause of vitiligo is not fully understood, but it is believed to involve a combination of genetic, autoimmune, and environmental factors. Here are key points about vitiligo:

Characteristics of Vitiligo:

1. White Patches: The primary symptom of vitiligo is the presence of depigmented or hypopigmented (white or light-colored) patches on the skin. These patches may vary in size and shape.

2. Symmetrical Distribution: Vitiligo often appears on both sides of the body in a symmetrical pattern, affecting corresponding areas.

3. Common Sites: While vitiligo can occur anywhere on the body, it often affects areas with higher sun exposure, such as the face, hands, arms, feet, and genital area.

4. Hair and Mucous Membranes: Vitiligo can also affect the hair, causing premature graying or loss of color, and mucous membranes, such as the mouth and nose.

5. Progression: The progression of vitiligo can be unpredictable. In some cases, the condition may progress slowly, while in others, it may progress rapidly.
