Sjögren's syndrome with nodular pulmonary amyloidosis.

We report a case of Sjögren's syndrome with nodular pulmonary amyloidosis. Amyloidosis is a heterogeneous group of diseases caused by aggregation of autologous protein and its extracellular deposition as fibrils. Most cases of nodular pulmonary amyloidosis are the result of an underlying disorder such as mucosa-associated lymphoid tissue lymphoma, rheumatoid arthritis, or multiple myeloma. Nodular pulmonary amyloidosis with Sjögren's syndrome is very rare. The clinical outcome of patients with nodular pulmonary amyloidosis is good if the underlying disease can be controlled.
