Norwegian scabies is an unusual Sarcoptes scabiei infestation. It has been reported often in patients who are either severely debilitated or who have congenital or iatrogenic suppression of their immune responses. We report the occurrence of Norwegian scabies in a 13-year-old boy with Bloom's syndrome who had impaired humoral and cell-mediated immunity.
