Scabies simulating Darier disease in an immunosuppressed host.
A patient who had recently had renal transplant was on a maintenance regimen of azathioprine and prednisone. She developed a florid, scaling, papular eruption clinically identical to Darler disease. Biopsy specimens and skin scrapings, however, showed a scabietic infestation. We believe that this highly atypical presenation, which had several features found in Norwegian scabies, was due to  muted inflammatory response that permitted a great proliferation of the mites.
