Waldenström’s Macroglobulinemia-Associated Renal Amyloidosis Presenting as a Solitary Lung Mass

Abstract

A single nodular lesion can be observed in various pulmonary diseases, including cancer, tuberculosis, and fungal infection. Waldenström’s macroglobulinemia (WM) usually occurs in older adults and involves the lymph nodes, bone marrow, and spleen. Respiratory tract involvement is very rare. We reported a case of WM-associated renal amyloidosis. The patient was admitted with the initial presentation as a single mass in the lung and progression to renal involvement.
