A Severe Case of Levamisole-Induced Vasculitis
Levamisole is a commonly utilized adulterant for illicit drugs such as cocaine. It has been associated with perinuclear anti-neutrophil cytoplasmic antibody (P-ANCA)-associated retiform purpura in cocaine users. It is important for clinicians to recognize the typical location and clinical presentation of these patients to reach a proper diagnosis. We present a severe case of levamisole-induced vasculitis in a cocaine user to highlight the classic clinical findings and the diagnostic evaluation for these patients.
