A case of fatalPemphigus Vulgaris in association with beta interferon and interleukin-2 therapy

Abstract
Beta interferon (β-IFN) and interleukin-2 (IL-2) have been utilized in experimental cancer therapy because of their effects on the immune system. We report here a patient treated with IL-2 and β-IFN who rapidly developed an immune-mediated, bullous exfoliative dermatitis and who ultimately died. Various etiologic mechanisms are proposed.
