title: Erythema elevatum diutinum in systemic lupus erythematosus.
abstract: Erythema elevatum diutinum (EED) is a rare chronic form of leukocytoclastic vasculitis with unknown etiology. EED has been described in association with hematological malignancies, infections and a number of rheumatological diseases. We report a patient with systemic lupus erythematosus (SLE) who presented with intermittent attacks of tender nodules and plaques on the shins and ankles for 6 months. Skin biopsy confirmed the diagnosis of EED. Treatment with dapsone resulted in complete resolution of the skin lesions. EED is rarely reported in SLE, and its presentation and treatment is reviewed.
