title: Crusted scabies and tinea corporis after treatment of presumed bullous pemphigoid.
abstract: We report a case of scabies that immunohistochemically mimicked bullous pemphigoid (BP) in an 82-year-old woman who presented with intractable pruritus. Bullous pemphigoid initially was diagnosed by direct immunofluorescence (DIF), though no blisters were clinically present. Subsequent immunosuppressive therapy for treatment of presumed BP led to the development of crusted scabies and widespread tinea corporis.
