Crusted scabies associated with systemic lupus erythematosus: response to benzyl benzoate therapy.
A 30-year-old Thai woman with systemic lupus erythematosus developed crusting, erythematous scaling plaques on the scalp and neck. Histologic section showed numerous mites in the stratum corneum. The diagnosis was further confirmed by identification of Sarcoptes scabiei in scraping and potassium hydroxide preparations made from the cutaneous lesions. After applications of 25 per cent benzyl benzoate for one month, there was complete resolution of the parasitic infestation.
