[Scabies-clinical resistance to permethrin therapy : Case reports and a critical discussion of current treatment recommendations].

Scabies is a contagious disease with increasing frequency. This is confirmed by data from insurance companies as well as increased search queries on Google. There is a controversial discussion in the scientific literature whether the mite has become resistant to standard therapy with permethrin. One case report and a group of cases (N = 12) from a mother-child facility are described in the following demonstrating decreased effectiveness of permethrin therapy. Dermatoscopy can be helpful in diagnosis and in assessing effectiveness of therapy. Dermatoscopic criteria are shown and therapeutic concepts are critically discussed.
