VITILIGO

Post by azmath on Sun Nov 18, 2007 7:01 pm

Hypopigmented and depigmented lesions favor sun-exposed regions, intertriginous areas, genitalia, and sites over bony prominences (type A vitiligo).
Areas around body orifices are also frequently involved.
The lesions tend to be symmetric.
Occasionally the lesions are linear or pseudodermatomal (type B vitiligo).
Vitiligo lesions may occur at trauma sites (Koebner's phenomenon).
The hair in affected areas may be white.
The margins of the lesions are usually well demarcated, and when a ring of hyperpigmentation is seen, the term trichrome vitiligo is used.
The term marginal inflammatory vitiligo is used to describe lesions with raised borders.
Initially the disease is limited, but the lesions tend to become more extensive over the years.
Type B vitiligo is more common in children. Vitiligo may begin around pigmented nevi, producing a halo (Sutton's nevus); in such cases the central nevus often regresses and disappears over time
