Bortezomib-induced Sweet's syndrome

Abstract

Sweet's syndrome is an uncommon acute skin disease, associated with a variety of medical problems. The drug-induced variant is even rarer. We describe two cases of this syndrome associated with the administration of the proteasome inhibitor bortezomib. The diagnostic criteria for drug-induced Sweet's syndrome as proposed by Walker and Cohen were fulfilled. Vasculitis and neutrophilic eccrine hidradenitis were excluded.
