penetration of acaricides, topical therapy may be insufficient, as Norwegian scabies is resistant and relapsing. 5 Oral ivermectin has been used safely and effectively for the treatment of Norwegian scabies in immunosuppressed patients, in doses ranging from 100-200 mg/kg, at 1-week intervals, for 1-3 times. 5,6 We did not use oral ivermectin as it is not available in our country. We used 5% permethrin cream, which has a wide margin of safety. Less than 2% of permethrin is absorbed percutaneously, and the drug is rapidly broken down. 7 Complete resolution of the lesions was observed after repeated applications of 5% permethrin cream combined with keratolytic therapy in our patient, and no side effects were observed.Early diagnosis of Norwegian scabies is important in the prevention of the spreading of the infestation as it is an extremely infectious condition. 6 Pruritus and crusted lesions in immunosuppressed patients should suggest the diagnosis of Norwegian scabies.
