Crusted scabies, an unusual clinical variant of human scabies mite infestation, is usually reported in cases of gross debility, mental deficiency, or immunosuppression. We report here the occurrence of crusted scabies in a 40-year-old man with acquired selective IgA deficiency suspected to be caused by long-term medication with phenytoin for epilepsy.
