Overview
Vitiligo constitutes one of the most frequent pigment disorders, affecting about 1% of the world's population, with no preference of race, age, gender, or country. It commonly starts to manifest around the second decade of life, with a gradual progress of depigmentation, mostly due to loss of melanocytes.[1][2]
History
Vitiligo is one of the most common diseases of depigmentation. It affects 0.5% to 1% of the world population, without preference for a particular race, gender, age or country. For patients presenting for the first time with patches of skin depigmentation, a thorough history and physical examination should be performed, including examination under the Wood's lamp in order to rule out other potentially life-threatening disorders. The initial onset of the condition may be abrupt, however, afterwards it usually progresses slowly, with expansion of skin depigmentation with no concomitant symptoms.[3][4][5][6] There may be two major subdivisions of vitiligo which may influence the presence of different characteristics and the natural history of the disease. They may be present individually or concomitantly, in which case the segmental lesions will respond poorly to the treatment:[3][7]
Generalized or Nonsegmental
- The most common form of the disease, present in about 85-90% of the cases.
- Common later onset.
- Continuous progression with periods of exacerbation.
- Hair is usually affected later in life.
- Individual or family history of other autoimmune diseases.
- Frequently occurs in areas of the body susceptible to trauma or keen to pressure.
- Bad response to autologous grafting, commonly recurring on the same location.
Segmental
- Commonly has an earlier onset in childhood.
- Has an abrupt onset, stabilizing afterwards.
- Rapidly evolves to involve hair regions.
- Commonly involves the face.
- Generally no other autoimmune diseases are present.
- May be confused with nevus depigmentosus.
- Commonly responds well to autologous grafts.
