1 Disorders of pigmentation
Disorders of pigmentation. A: Postinflammatory hypopigmentation after resolution of eczematous patches in a patient with atopic dermatitis. B: Phytophotodermatitis presenting as streaks of hyperpigmentation at the sites of drips from a lime squeezed by this child while on the beach in Jamaica. C: Depigmented patches of vitiligo on the knee with both white hairs and (in areas with pigmented hairs) perifollicular repigmentation. D: Multiple hypopigmented patches that represent nevus depigmentosus. E: Hypomelanosis of Ito. Note the swirls of macular hypopigmentation following the lines of Blaschko. Source: Chapter 361.
