title: [A case of inflammatory myopathy worsened by miscarriage with autoimmune disorder-associated disease].
abstract: The patient was 42-year-old woman who had exhibited elevated levels of serum creatine kinase(CK) and intermittent weakness of proximal muscles since her thirties. She had a history of palmoplantar pustulosis, Mondor's disease and recurrent miscarriages. Basedow's disease, which had been treated with antithyroid drugs since 37 years of age, recurred during the fourth pregnancy. After the pregnancy was terminated in the sixth week, weakness and grasp pain in the proximal muscles developed. The biopsy of biceps brachii muscle showed necrosis and reconstruction of muscle fibers with equivocal inflammatory cells, which was compatible with the findings for inflammatory myopathy such as polymyositis(PM). She was treated with prednisolone and the weakness and grasp pain in the proximal muscles were resolved. PM beginning during a woman's reproductive period is rare, and few studies have examined the association between PM and pregnancy. In this case, pregnancy and her past diseases were considered to be linked to an autoimmune abnormality that might have contributed to the inflammatory myopathy.
