쇼그렌증후군에서 염증근육병과 동시에 나타난 중증근무력증

Abstract

Myasthenia gravis (MG) and inflammatory myopathy are both rare autoimmune disorders that present with signs ofmuscle weakness and can sometimes be accompanied by other connective-tissue diseases such as Sjögren’s syndrome. However, the simultaneous occurrence of MG and inflammatory myopathy is very rare. We describe the case of a68-year-old woman with MG occurring simultaneously with inflammatory myopathy in Sjögren’s syndrome.
