Organizing pneumonia as the first manifestation of anti-synthetase syndrome.

BACKGROUND

Anti-synthetase syndrome associated interstitial lung disease can occur either simultaneously, before, or after the development of polymyositis/dermatomyositis. Histology of interstitial lung disease can be nonspecific interstitial pneumonia, usual interstitial pneumonia, diffuse alveolar damage, organizing pneumonia. Organizing pneumonia associated anti-synthetase syndrome is a rare finding especially as the first manifestation.

CASE PRESENTATION: We report a 41 year old male patient who presented with organizing pneumonia and 2 years following the onset, developed polymyositis with anti-JO-1 antibody positivity.

CONCLUSION

It is important to screen patients with organizing pneumonia for anti-synthetase syndrome which can be manifested later.
