Vitiligo Types

Vitiligo is an auto-immune skin condition that causes loss of pigmentation, resulting in the formation of white patches on the skin.

Types of vitiligo:

  1. Non-segmental Vitiligo: This is the most common type of vitiligo, accounting for about 90% of cases. Non-segmental vitiligo can be further classified into the following subtypes:
  • Generalized Vitiligo: This subtype is characterized by the presence of white patches on different parts of the body, including the face, hands, feet, arms, and legs. The patches tend to be symmetrical and may increase in size over time.
  • Acrofacial Vitiligo: This subtype affects the fingers and toes, as well as the area around the mouth, nose, and eyes. It is more common in people with darker skin tones.
  • Mucosal Vitiligo: This subtype affects the mucous membranes, such as the lips, genitals, and anus. It may occur in conjunction with other types of vitiligo.
  1. Segmental Vitiligo: This type of vitiligo affects only one side or a specific area of the body. It is less common than non-segmental vitiligo and tends to occur earlier in life. Segmental vitiligo can be further classified into the following subtypes:
  • Focal Vitiligo: This subtype affects a small area of the body, such as the face, neck, or trunk.
  • Segmental Vitiligo: This subtype affects a specific segment of the body, such as one arm or leg.
  • Mucosal Vitiligo: This subtype affects the mucous membranes, such as the lips, genitals, and anus.

Segmental vitiligo tends to be more stable than non-segmental vitiligo, with fewer chances of progression. It is also less responsive to treatment compared to non-segmental vitiligo.

It is important to note that vitiligo can also be classified based on its progression:

  • Progressive Vitiligo: This type of vitiligo is characterized by the gradual enlargement of existing patches or the appearance of new patches.
  • Stable Vitiligo: This type of vitiligo is characterized by the absence of new patches or enlargement of existing patches for at least six months to 3 years (based on different authors in scientific literature.)

Overall, the type of vitiligo a person has can determine the course of treatment and its effectiveness. It is important to consult with a dermatologist for a proper diagnosis and treatment plan.
