浆细胞瘤(plasmacytoma)是一组来源于B淋巴细胞,表现为浆细胞单克隆增殖的罕见肿瘤,临床分型包括浆细胞性骨髓瘤,又称多发性骨髓瘤(mutiple myeloma,MM);骨孤立性骨髓瘤(solitary plasmacytoma of bone,SPB),髓外浆细胞瘤(extramedullary plasmacytoma,EMP)及冒烟型骨髓瘤,不分泌性骨髓瘤,骨硬化型骨髓瘤,双克隆及三克隆型骨髓瘤,且后者均可称为多发性骨髓瘤的变异型[1]。 Plasmacytoma is a rare group of neoplasms derived from B lymphocytes that proliferate in plasma cells. The clinical classification includes plasmacytoma, also known as multiple myeloma (MM); bone Solitary plasmacytoma of bone (SPB), extramedullary plasmacytoma (EMP) and smoldering myeloma, non-secreting myeloma, osteosclerosis, myeloma, bi-clonal and tri-clonal bone marrow Tumor, and the latter can be referred to as multiple myeloma variant [1].
