IntroductionExtramedullary plasmacytoma (EMP) is an uncommon tumor that often develops outside the bone and arises from clonal proliferation of atypical plasma cells before EMP is diagnosed. Multiple myeloma(MM) must be excluded by performing laboratory tests such as serum protein electrophoresis, bone marrow biopsy and skeletal imaging ex-aminations. A bone marrow biopsy should show no evidence of mul-tiple 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 pre-dominantly affects the head and neck areas. Any extra-osseous organ may also be involved[1,2]. Tracheal involvement is a rare finding. Only a few cases of primary tracheal extramedullary plasmcytoma have been reported[2-4], Here we present a rare case of truly localized tra-cheal extram edullary plasmacytoma without evidence of myelomaelsewhere.
