浆细胞瘤是以浆细胞异常增生为特征的恶性肿瘤,约占浆细胞源性肿瘤的5%~10%。其通常分为浆细胞性骨髓瘤(多发性骨髓瘤,multiple myeloma,MM),髓外浆细胞瘤(extramedullary plasmacytoma,EMP)和骨孤立性浆细胞瘤(solitary plasmacytoma of bone,SPB)3类,临床以MM多见,而SPB较少见[1,2]。患者男,58岁,主因“右上胸壁占位10年,迅速增大2年”就诊。胸部CT平扫示右侧锁骨走行区见一不规则软组织肿块,大小约10.8 cm×9.6 cm×5.6 cm,界限欠清晰,内
Plasmacytoma is a malignant tumor characterized by abnormal proliferation of plasma cells, accounting for about 5% to 10% of plasmacytoid tumors. It is usually classified into three groups: plasma cell myeloma (multiple myeloma, MM), extramedullary plasmacytoma (EMP) and solitary plasmacytoma of bone (SPB) Clinical MM more common, while the SPB is rare [1,2]. Male patient, 58 years old, mainly due to “right upper chest wall occupy 10 years, rapidly increasing 2 years ” treatment. Chest CT scan revealed an irregular soft tissue mass on the right side of the clavicular area with a size of about 10.8 cm × 9.6 cm × 5.6 cm with less clear boundaries
