A case of Sweet's syndrome treated with potassium iodided

Abstract

Sweet's syndrome(acute neutrophilic dermatosis) is characterized by raised, painful red plaques with pseudoblistering and pustules on the face, neck, chest, and extremities accompanied by fever, polymorphonuclear neutrophilic leukocytosis, and elevated ESR. We report a case successfully treated with potassium iodide in which showed tender indurated erythematous papules, nodules, plaques, and several overlying vesicles with fever and general malaise. These lesions had frequently recurred in spite of oral corticosteroid administration for 5 months at a local clinic. The cutaneous eruptions subsided 7 days after administration of a saturated potassium iodide solution and have not recurred to date.
