Successful treatment of relapsing neuro-Sweet's disease with corticosteroid and dapsone combination therapy.

Sweet's disease with central nervous system involvement, tentatively named neuro-Sweet's disease, has rarely been reported. Although systemic corticosteroid therapy is highly effective for neurologic symptoms in neuro-Sweet's disease, relapse is common. Here, we describe the case of a 38-year-old Japanese man who presented with relapsing neuro-Sweet's disease that was successfully treated with a combination of corticosteroid and dapsone. Dapsone should be considered as a therapeutic option for neuro-Sweet's disease patients showing relapse.
