Cocaine-induced pyoderma gangrenosum–like lesions: Levamisole may be not the only culprit. Report of three cases and review of the literature

Background: Cocaine-induced pyoderma gangrenosum-like (CIPG), cocaine-induced midline destructive lesions (CIMDL), and retiform purpura (RP) are some of the mucocutaneous manifestations associated with cocaine consumption, the latter initially described in patients consuming cocaine adulterated with levamisole. It is estimated that up to 80% of cocaine is contaminated with levamisole.
