[A case of Sjögren's syndrome with a clinical course similar to diffuse panbronchiolitis].

A 64-year-old man was admitted because of some infection of the airway. Chest roentgenography showed a bilateral reticulonodular shadow which was similar to the shadow of DPB. Pathological findings obtained by lung biopsy indicated bronchiolitis. This case was diagnosed as Sjögren's syndrome because of the increase of titers of anti-ssA and anti-ssB antibody, lachrymal dysfunction, pathological findings and sialography. The relationship between DPB and lung lesions of Sjögren's syndrome was investigated.
