[A case of Sjögren syndrome with pulmonary nodular amyloidosis and pulmonary multiple cysts].

A 57-year-old woman who had been given a diagnosis of Sjögren syndrome at age 53 consulted a nearby doctor because of bloody sputum. He noted her chest abnormal shadows and referred her to our hospital. Her chest radiograph and high-resolution computed tomograph showed multiple nodules and cysts in both lung fields. Video-assisted thoracoscopic lung biopsy revealed patchy fibrosis, cystic change, AL type amyloid deposition and mild lymphoid hyperplasia and a diagnosis of Sjögren syndrome-associated-pulmonary-disease was established.
