A 32-year-old woman presented complaining of a recurrent, very itchy, papular, blistering rash. It had appeared over her knees, elbows, buttocks and scalp. She had applied calamine lotion and tried an oral antihistamine, without benefit. On examination there were obvious papules, vesicles and blisters and excoriated lesions over the buttocks and upper thighs and signs of scars from scratch marks in other areas.
