The Cocaine Trail: Levamisole-Induced Leukocytoclastic Vasculitis in a Cocaine User

This is the authors' abstract. We don't add key points for this paper.

Two million Americans use cocaine on a regular basis. Sixty-nine percent of cocaine in the United States is adulterated with levamisole, a veterinary antihelminthic drug. In 2008, the first cases of levamisole-induced agranulocytosis and vasculopathy associated with adulterated cocaine were reported in the southwestern United States. Since then, reports of levamisole-associated toxicity have become increasingly common. The authors present the case of a 47-year-old woman from Michigan with purpuric lesions likely secondary to levamisole-induced leukocytoclastic vasculitis.
