title: Granulomatous vasculitis as a complication of potassium iodide treatment for Sweet's syndrome.
abstract: A case of Sweet's syndrome treated with potassium iodide is hereby described. The patient responded well a few days after the initiation of therapy, but the evolution was complicated with a severe clinical deterioration two weeks later. Systemic vasculitis was diagnosed on the basis of significant impairment of renal function, involvement of the eyes (papillitis) and the skin biopsy which showed a leukocytoclastic vasculitis. This systemic vasculitis was attributed to the potassium iodide therapy.
