Abstract
|
|
|
Erythema elevatum diutinum is a relatively ratre disease of unknown etiology. It is charaterized by persistent erythematous plaque and nodule that are usually affected symmetrically over extensor surface of extremities.
Our patient, a 16-year-old female was referred for evaluation of asymptomatic papules and nodules on extensor aspects of the hands, legs and buttocks. She complained of arthralgia on the knees. The laboratory values were all within normal limits
with
the exception of slight elevation of white blood cell counts and erythrocyte sedimentation rate. A skin biopsy specimen was obtained from the nodular lesion of the leg that showed predominantly perivascular neutropilic infiltration with
occasional
lymphocytes and unclear dusts. She was treated with 75mg/day of dapsone. Skin lesions were much improved after ten days. Eight weeks later, the lesion had almost resolved. After the discontinuation of dapsone, new lesions developed on the legs.
Retreatment with dapsone resulted in a dramatic response of her lesions after three weeks. (Kor J Dermatol 1993;31(6) : 968-972)
