The idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by chronic inflammation, resulting in the progressive weakness of the proximal muscles. Myositis-specific or myositis-associated autoantibodies can often be found in serum of polymyositis and dermatomyositis patients. This autoantibody presence may play a significant role in patient diagnosis and classification. We present a female polymyositis patient characterized with serious muscle weakness and lung involvement. Anti-Jo1 antibodies were detected in the patient’s serum at the time of diagnosis. After 5 years of treatment and surveillance, recent laboratory analysis showed the presence anti-SRP antibody in her serum.
