分裂象在淋巴结反应性增生鉴别中的意义

探索与掌ＬＲＨ组织学改变特点及规律。方法显微镜下观察９５例ＬＲＨ的组织结构，核分裂，大细胞及浆细胞等的变化。采用ＳＰＳＳ软件进行统计处理。结果滤泡增多，滤泡外淋巴组织增生是ＬＲＨ中最常见的淋巴结组织不结构紊乱，占６５．２％。ＬＲＨ中滤泡外淋巴组织内裂象比较常见，一个高倍视野核分裂象１－３个的出现率达５４．７％（５２／９５），但均是正常核发裂，滤泡内核分裂与滤泡外核分裂有轻度相关。相关系数为ｒ＝０．

Significance of Mitotic Figures in Differential Diagnosis of Reactive Lymphoid Hyperplasia

Objective To study the histopathological characteristics of reactive lymphoid hyperplasia in lymph nodes. Methods Karyokinesis, large cells, plasma cell and structural changes were observed in 95 cases of lymphnode reactive hyperplasia. SPSS software was used for statistic analyses. Results Hyperplasia of the follicles and proliferation of other lymphoid tissues of outside follicles are the most common changes (65.2%). Mitosis was easily seen in the lymphoid tissues of outside follicles, 1 3/HPF (54.7%). There was a relationship in the number of mitotic figures between follicles and other lymphoid tissues (r=0.302; P <0.01). Plasma cells were observed in 42 of 95 cases and the large cells appeared at 15.8% cases. Conclusion Recognition of the histologic features is crucial to diagnosis and differential diagnosis of reactive lymphoid hyperplasia.
