A pseudoepithelial pattern was observed in smears prepared from fine needle aspirates (FNA) from three plasmacytomas. In one case cells displayed a markedly granular, 'oncocytic' cytoplasm. Granularity of the cytoplasm was due to a large number of mitochondria as shown by electron microscopy. B-lymphocytic origin of the neoplasms was confirmed by immunocytochemistry.
在取自三个浆细胞瘤的细针穿刺抽吸物（FNA）制备的涂片上观察到假上皮样模式。在一个病例中，细胞显示出明显颗粒状的“嗜酸性”细胞质。电子显微镜显示，细胞质的颗粒状是由于大量线粒体所致。免疫细胞化学证实了肿瘤的B淋巴细胞起源。
