Primary endobronchial plasmacytoma involving local lymph nodes and presenting with rare immunoglobulin G lambda monoclonal gammopathy.
Extramedullary plasmacytoma occurring as a primary pulmonary lesion is rare. The present report describes a 42-year-old Chinese man diagnosed with primary pulmonary plasmacytoma following left lower lobectomy. Of note, an extremely rare immunoglobulin G lambda paraprotein was documented in the patient's serum by immunofixation electrophoresis.
