Methods: One patient with tracheal plasmocytoma and pertinent literature were analyzed retrospectively. Results: Resection of the tracheal tumor and reconstruction of the trachea were performed successfully in this case, and the pathological diagnosis is plasmocytoma. Conclusion: The nature, location and extent of tracheal tumor are precisely determined from radiologic studies before resection, as well as tracheal intubation and tracheal anastomosis without tension in operative procedures, are very important for triumphal operation. Even extramedullary plasmocytoma may occur in a lot of organs, but the incidence of it is rare. Both surgery and radiotherapy are cardinal methods for extramedullary plasmocytoma.展开更多

Multiple myeloma （MM） must be excluded by performing laboratory tests such as serum protein electrophoresis, bone marrow biopsy and skeletal imaging examinations. A bone marrow biopsy should show no evidence of multiple myeloma, and less than 3% of plasma cells. Monoclonal bands of serum protein and Bence-Jones protein in the urine can sometimes be detected. EMP can involve any extraosseous organs, but it predominantly affects the head and neck areas. Any extra-osseous organ may also be involved. Tracheal involvement is a rare finding. Only a few cases of primary tracheal extramedullary plasmcytoma have been reportedE2-41, Here we present a rare case of truly localized tracheal extramedullary plasmacytoma without evidence of myeloma elsewhere.展开更多
