Case ReportsThe pulmonary histopathology of anti-KS transfer RNA synthetase syndrome.
The clinical spectrum of the antisynthetase syndromes (AS) has been poorly defined, although some frequently present with pulmonary manifestations. The anti-KS anti-asparaginyl-transfer RNA synthetase syndrome is one in which pulmonary interstitial lung disease is almost always present and yet the histopathologic spectrum is not well described. ⋯ Pulmonary interstitial lung disease is a common presentation in patients with the anti-KS-antisynthetase syndrome, who are often women with rather subtle or subclinical connective tissue disease, whereas the literature emphasizes the nonspecific interstitial pneumonia pattern often diagnosed clinically. Usual interstitial pneumonia and organizing pneumonia patterns of interstitial injury need to be added to this clinical differential diagnosis.
