Hypersensitivity angiitis is one of the commonest necrotising vasculitides. Given the ubiquitous distribution of the small blood vessels almost any part of the body may be affected. However benign forms predominantly involving the skin are the most common. Forms predominantly involving the viscera and that may prove fatal are rare. Among the polymorphous skin lesions encountered "palpable purpura" is the most common and its palpability is a vital element in differential diagnosis. Among non-cutaneous sites the kidneys are the most frequent and glomerular involvement is the commonest cause of death. Though laboratory tests provide no specific data they may indicate the severity of visceral involvement.
超敏性血管炎是最常见的坏死性血管炎之一。鉴于小血管分布广泛，身体几乎任何部位都可能受累。然而，主要累及皮肤的良性形式最为常见。主要累及内脏且可能致命的形式很少见。在多形性皮肤病变中，“可触及的紫癜”最为常见，其可触及性是鉴别诊断的关键因素。在非皮肤部位中，肾脏受累最为常见，肾小球受累是最常见的死亡原因。虽然实验室检查不能提供具体数据，但它们可能提示内脏受累的严重程度。
