Abstract

Though the polymyositis, one of the common adult-onset myopathy, is treatable, the diverse clinical manifestation and course sometimes lead the clinician to incorrect diagnosis. Here we report a case of polymyositis, presented with atypical features and diagnosed as muscular dystrophy on muscle biopsy previously, but showed marked clinical improvement after combined treatment with prednisolone and methotrexate.
