title: Solitary extramedullary plasmacytoma presenting as an endobronchial mass.
abstract: Solitary extramedullary plasmacytoma (SEP) is a plasma cell neoplasm that develops outside of the bone marrow. A solitary, exophytic growth in the airway is an extremely rare presentation of SEP. We herein report a case of SEP presenting as an endobronchial mass. The tumor was treated by rigid bronchoscopic debulking followed by ablation using argon plasma coagulation. However, the tumor could not be completely removed due to its wide base. Adjuvant radiotherapy was administered as the curative therapy. A biopsy was performed on the resected specimen and the diagnosis of plasmacytoma was thereby confirmed.
