dapsone is a drug primarily used for the treatment of hansenˋs disease, and it has also been employed in cases of bullous lupus erythematosus and some types of cutaneous vasculitis. recently, its efficacy in the treatment of cutaneous lesions in dermatomyositis has been observed. we present two cases of dermatomyositis, amyopathic form, which were refractory to habitual treatment, but had an excellent response to dapsone therapy.
