title: [Diagnostic difficulties in polymyositis].
abstract: Polymyositis is a connective tissue disease. Although myositis is the dominant clinical manifestation, internal organs may also be affected. Arthritis occurs in 30% of patients, especially in the course of the anti-synthetase syndrome. We report on a case of a woman with polymyositis and interstitial lung disease. Arthritis and the presence of anti-cyclic citrullinated peptide antibodies in the patient's serum may suggest the diagnosis of the overlap syndrome.
