Antituberculosis therapy-associated cutaneous leukocytoclastic vasculitis

摘要

Antituberculosis therapy-associated cutaneous leukocytoclastic vasculitis (CLV) has been rarely reported. We describe a case of CLV induced by rifampicin and pyrazinamide. A 14-year-old male diagnosed with disseminated tuberculosis developed purpuric lesions after 1.5 months of treatment. Histopathology was consistent with leukocytoclastic vasculitis. Skin lesion improved after cessation of the two drugs and treatment with corticosteroids.
