Physical examination revealed only mild pale conjunctiva. The workup showed mild anaemia, mild impaired renal function, and high globulin level. Multiple myeloma was excluded by normal serum protein electrophoresis. The chest radiography and computed tomography (CT) revealed bilateral multifocal patchy infiltration with mediastinal adenopathy. Bronchoscopy was performed. Bronchoalveolar lavage (<jats:styled-content style=\"fixed-case\">BAL<\/jats:styled-content>) fluid examination was negative for infection and malignancy. Tissue pathology revealed diffuse lymphoplasmacytic cell infiltration.
