We describe here a rare case of primary extramedullary plasmacytoma of the lung in an 86-year-old Japanese man. Immunohistochemical staining of biopsy specimens for IgG-kappa was positive, and serum immunoelectrophoresis showed monoclonal IgG-kappa. There was no evidence of the presence of multiple myeloma. Chemotherapy was given, but tumor size did not decrease significantly.
