title: [A long-term case of Sjögren's syndrome with pulmonary multiple cystic lesions].
abstract: A 68-year-old woman was admitted to our institution's respiratory section because of dyspnea on effort in January, 2007. She had previously received a diagnosis of Sjögren's syndrome because of dryness in her eyes in 1991. Chest radiography and chest CT in 2001 revealed diffuse multiple cystic lesions in both lungs which had progressed gradually for 6 years. Biopsy specimens obtained by video-assisted thoracoscopy showed lymphoid hyperplasia with follicular bronchiolitis and lymphocytic alveolitis. Narrowing of the small airways and obstructive lung disease with multiple bullae were observed and we suspected them to be related to peribronchiolar lymphocytic infiltration. These were lung involvements associated with Sjögren's syndrome. The patient's cystic lesions gradually worsened despite the administration of corticosteroid and cyclophosphamide. Cystic lesions in Sjögren's syndrome may be a treatment-resistant finding.
