title: [A case of multiple nodular pulmonary amyloidosis complicated with primary Sjogren syndrome].
abstract: A 79-year-old woman was admitted to the Department of Orthopedics Surgery for treatment of osteoarthritis in her knee. Multiple pulmonary nodular lesions were found on preoperative chest x-ray film screening. Metastatic lung tumor was suspected, but no tumorous lesions were detected in other organs. CT guided lung biopsy was performed. Histopathological examination revealed amyloid consisting of homogenous eosinophilic materials. No amyloid deposits were detected in other organs, so we diagnosed localized nodular pulmonary amyloidosis. She was subsequently given a diagnosis of primary Sjögren syndrome. We believe that such a case of multiple nodular pulmonary amyloidosis with Sjögren syndrome is rare, and the case showed interesting radiological findings, such as mimicking metastatic lung tumor.
