We report a case of erythema elevatum ditinum in a 6-year-old girl. Th symmetrically distributed skin lesions consisted of elevated purplish annular plaques and nodules on the elbows, knees, ankles and buttocks, and some of the lesions showed vesicles, hemorrhagic crusts, and necroses. Biopsy specimens from the knee and ankle revealed typical leukocytoclastic vasculitis. Ve performed a Multites CMI, a test for delayed r.utaneous hypersensitivity, in which the patient showed positive reaction to streptococcal antigen(Lancefield group C). We tried oral prednisolone and dapsone seperately and could see a remarkable response to both drugs.
