Scabies Surrepticius (Presenting as Crusted-Norwegian-Scabies, Scalp Scabies, and Scabies Incognito) in an Immunocompromised Patient: A Challenging Condition to Diagnose and Treat

摘要

Dear Editor:I read with interest the excellent report by Zhang et al.1 of a 55-year-old woman with Norwegian scabies(which is also referred to as crusted scabies)that masqueraded as scalp seborrheic dermatitis for 5 months until the correct diagnosis was established.The authors attributed her immunosuppressed state-which accounted not only for the crusted scabies but also its location on her scalp in addition to other body areas-to a chronic hepatitis C infection.Her mite infestation also had a component of scabies incognito from the application of high-potency topical corticosteroids(0.05%fluticasone propionate cream and 0.1%halcinonide solution)for 5 months.
