[A man with severe skin rash].

A 31-year-old man visited the outpatient clinic Dermatology with an exacerbation of his atopic eczema. Since a few day vesicles and crusts had appeared and his eyelids were swollen. He was known to have eczema, for which he was treated with ciclosporin 200 mg 2 times a day (4 mg/kg per day) since four months. Under this treatment the eczema used to be under control. There were no neurological symptoms or vision problems. At physical examination we saw erythematous papules, vesicles, superficial erosions and crusts on all body regions, but especially on the trunk and in the main neck region. The patient was diagnosed with eczema herpeticum and he was treated with intravenous aciclovir 1000 mg 3 times a day (10 mg/kg 3 dd) and flucloxacillin 1000 mg 4 times a day for seven days.
