title: Immunological diagnosis of cutaneous-pulmonary hypersensitivity vasculitis.
abstract: A 47-year-old woman had episodic dyspnoea, fatigue, chest radiograph opacifications, and palpable purpura whose biopsy showed leucocytoclastic vasculitis. Negative immunoglobulin A immunofluorescence staining and clinical exclusion of other disorders narrowed her diagnosis to cutaneous pulmonary hypersensitivity vasculitis.
