Potassium iodide in refractory, recurrent pediatric Sweet syndrome: Guidance in dosing and monitoring

Abstract

We describe a 5-month-old boy with clinical and histopathologic presentation of Sweet syndrome. He responded to systemic corticosteroids, with multiple flares on tapering; potassium iodide was added, which provided complete resolution of Sweet syndrome. Potassium iodide has been used in only a few cases, and no standard dosage has been established in children. We discuss calculation of a pediatric dosage for potassium iodide in Sweet syndrome.
