title: Onset of myasthenia gravis in a patient affected by rheumatoid arthritis never treated with disease-modifying anti-rheumatic drugs.
abstract: We describe a patient affected by rheumatoid arthritis (RA) that developed myasthenia gravis (MG) after 20 years of illness. The peculiarity of this case concerns both the rare association between these diseases and the fact that the patients had never assumed disease modifying antirheumatic drugs. These treatments have been associated in some clinical reports with the onset of MG during the clinical course of RA. To our knowledge this is the first case described in medical literature up to now.
