title: Itching purpura.
abstract: Itching purpura is a benign disorder characterized by the sudden onset of markedly pruritic, purpuric lesions with a clinical appearance similar to the progressive pigmented purpuric dermatoses. The pruritus is severe and unremitting and may lead to depression and loss of sleep. Hematologic and serologic evaluation is normal in most cases. The disease tends to be chronic with exacerbations and remissions lasting over a period of months to years. No current therapy has been uniformly successful in treating itching purpura.
