[Steroid-induced scabies norvegica].

Two patients aged 50 and 84 years presented with generalized itching eczema that has been treated with external and internal steroids for months. Despite therapy, the condition worsened continuously. Examination of skin scrapings revealed numerous mites, so Norwegian scabies was diagnosed. General examinations excluded underlying diseases. Treatment with steroids over months most likely led via immunosuppression to the exacerbation of the disease.
