In susceptible persons, this combination of drugs leads to a clinical syndrome that can include leukopenia and cutaneous manifestations. Many patients also demonstrate positive autoimmune markers. Biopsies of skin lesions often reveal a thrombotic pattern, leukocytoclastic vasculitis, or both. We report 2 cases of this clinical phenomenon, one of which was severe enough to require skin grafting. It is important for clinicians be aware of this emerging public health threat.</style></abstract></record></records></xml>
