虽然滤泡中心是浆细胞前体的产生场所,但滤泡中心细胞(FCC)淋巴瘤中的浆细胞分化很少见到,可能是因为大的无裂FCC的分化中的“阻断”。作者回顾了大量此类病例,以确定FCC淋巴瘤中浆细胞分化的频率。在198例连续两年的滤泡型FCC淋巴瘤中,发现17例(9%)病例中有大量浆细胞。石蜡包埋切片(PIP)的细胞质免疫球蛋白的免疫过氧化物酶研究显示,在这些和单型浆细胞群体在7个多型标记。在后一组中,浆细胞和FCC群体的同种型相同标记可以在三种情况下用免疫过氧化物酶(其中FCC显示细胞质标记)和一种情况下(一种测试)用表面分型研究证明。此外,3例患者的血清副蛋白与浆细胞胞质免疫球蛋白相同。这些研究结果表明,一小部分FCC淋巴瘤含有足够的浆细胞是一个诊断问题,在这些情况下,浆细胞是FCC淋巴瘤的分化成分。
Although follicular centers are the sites of production of plasma cell precursors, plasmacytic differentiation in follicular center cell (FCC) lymphomas is rarely seen, presumably because of a “block” in differentiation of the large noncleaved FCC. The authors reviewed a large number of these cases to determine the frequency of plasmacytic differentiation in FCC lymphomas. In one hundred ninety-eight, consecutive FCC lymphomas with a follicular pattern from a two-year period, 17 (9%) cases were found in which there were large numbers of plasma cells. Immunoperoxidase studies of paraffin-embedded sections (PIP) for cytoplasmic immunoglobulin showed polytypic marking in ten of these and a monotypic plasma cell population in seven. In this latter group, isotypically identical marking of the plasma cell and FCC populations could be demonstrated in three cases with immunoperoxidase (where the FCCs showed cytoplasmic marking) and in one case (of one tested) with surface typing studies. In addition, three patients had serum paraproteins identical to the plasma cell cytoplasmic immunoglobulins. These findings indicate that a small minority of FCC lymphomas contain sufficient plasma cells to be a diagnostic problem, and that in some of these cases, plasma cells are a differentiated component of the FCC lymphomas.
