A 56-year-old woman had solitary plasma-cell myeloma in the right humerus. Six weeks after local irradiation therapy, she died from pulmonary alveolar hemorrhage and bilateral pleural effusion with malignant plasma-cell infiltration of the right atrium. Ultrastructural studies of the plasma cells from the myocardium demonstrated large bundles of prominent, non-branching, solid cytoplasmic fibrils in many cells. Each fibril had a width of 66--132 A, periodicity of 30--60 A, and a beaded appearance. These features suggest that the fibrils may be protein material, possibly an immunoglobulin.
一名56岁女性右肱骨患有孤立性浆细胞骨髓瘤。局部放疗六周后，她死于肺泡出血、双侧胸腔积液以及右心房恶性浆细胞浸润。对心肌中的浆细胞进行超微结构研究发现，许多细胞内有大量突出的、无分支的实心细胞质纤维束。每条纤维宽度为66 - 132埃，周期为30 - 60埃，呈串珠状外观。这些特征表明这些纤维可能是蛋白质物质，可能是一种免疫球蛋白。
