本文对两例多发性骨髓瘤和一例多发性骨髓瘤继发浆细胞性白血病进行了电镜观察。结果表明:MM细胞与PCL细胞不存在有诊断意义的超微结构差异,部分MM细胞和PCI细胞胞浆内都出现了丰富的微丝,可能与细胞的来源和分化程度有关。
In this paper, two cases of multiple myeloma and one case of multiple myeloma secondary plasma cell leukemia were observed by electron microscopy. The results showed that there was no diagnostic ultrastructural difference between MM cells and PCL cells. Some MM cells and the cytoplasm of PCI cells appeared abundant microfilaments, which may be related to the origin and differentiation of cells.
