title: Cutaneous IgA-associated vasculitis induced by alcohol.
abstract: A patient with elevated levels of serum IgA developed purpuric lesions histologically resembling Henoch-Schönlein purpura brought on by consuming alcohol. Alcohol challenge with 5 units of alcohol reproduced the lesions, with a rapid rise of circulating CD4+ and CD8+ T cells followed by a fall of serum IgA and C3 concentration. The skin lesions and serum abnormalities resolved spontaneously within 6 weeks of the alcohol challenge.
