title: A case of solitary pulmonary nodular amyloidosis with Sjögren's syndrome.
abstract: Patients with Sjögren's syndrome frequently have pulmonary involvement, but the involvement of nodular pulmonary lesions, including pulmonary amyloidosis, is rare. Most cases of pulmonary amyloidosis involve multiple nodules; solitary pulmonary nodular amyloidosis, as an associated condition of Sjögren's syndrome, is very rare.In our report, we present the case of an 80-year-old female with Sjögren's syndrome who was incidentally found to have a small solitary pulmonary nodule. The nodule showed high fluorodeoxyglucose uptake and contained areas of calcification. Because the probability that the nodular lesion was malignant could not be excluded, the tumor was excised using a thoracoscopic procedure; the final diagnosis was pulmonary nodular amyloidosis. Although most cases of pulmonary amyloidosis involve multiple nodules, amyloidosis should be considered in the differential diagnosis for a solitary pulmonary nodule in patients with Sjögren's syndrome.
