Alcohol-Associated Immunoglobulin A Vasculitis: A Case Report and Review of the Literature

Immunoglobulin A (IgA)-mediated leukocytoclastic vasculitis is a cutaneous small-vessel vasculitis characterized by skin findings of palpable purpura. It may occur secondary to infections, neoplasms, drugs, and systemic conditions, although it is most commonly idiopathic. A known, but rare, trigger for IgA vasculitis is alcohol consumption. We present a case of a man with IgA vasculitis associated with alcohol use and review the literature on alcohol-associated vasculitis. Although rarely reported, alcohol-associated IgA vasculitis is an important entity to consider for appropriate diagnosis and management of such patients.
