[Digital arteritis, thrombosis and hypereosinophilic syndrome: an uncommon complication]

Abstract

Digital necrosis has been exceptionally described in association with the hypereosinophilic syndrome. We report a case of a smoking patient with idiopathic hypereosinophilic syndrome who developed digital arteritis with necrosis. A radial artery biopsy confirmed the vasculitis with inflammatory infiltrates which were predominantly eosinophilic granulocytes. The eosinophils may have an active role in the development of the vasculitis.
