Pulmonary amyloidosis in Sjögren's syndrome: a rare diagnosis for nodular lung lesions.

Lung involvement in Sjögren's syndrome (SS) can affect trachea, bronchus, small airways, pleura and may cause interstitial lung injury. It may also be associated with malignancies, particularly non-Hodgkin's lymphoma, which is a well-recognized complication of this disease. Here we describe the occurrence of localized amyloidosis presenting as pulmonary nodules in a patient with newly diagnosed SS. We highlight this rare occurrence as a diagnostic possibility that should be considered in the evaluation of pulmonary involvement in this disease.
