Sixteen patients with primary Sjogren's syndrome (1-degrees-SS) who co
mplained of dyspnea were investigated with high resolution computerize
d tomography of the thorax, bronchoalveolar lavage, and transbronchial
biopsy. Six patients had evidence of interstitial fibrosis, 5 had a p
eribronchiolar lymphocytic infiltration and 3 had pleural thickening.
We conclude that significant pulmonary disease is not uncommon in pati
ents with 1-degrees-SS.
