感谢Dr. fawn28提出很好的问题供大家学习和思考,这个问题其实对理解AILT 极其鉴别诊断有比较重要的作用。2002年国际顶尖的血液病杂志“Blood”的一篇英国的研究小组的论文对这个问题进行了系统、深刻的阐述,后来此文也成为编写WHO第四版AILT相关内容的参考文献:
Neoplastic T cells in angioimmunoblastic T-cell lymphoma express CD10. Blood. 2002 Jan 15;99(2):627-33.
此文简单总结:CD10+的T细胞见于90%的AILT,阳性比例5-30%不等,但未见于外周T和反应性增生。
当然,不同的研究结果也并不完全相同,实验方法也产生一定的区别,因此,第四版WHO综合性地将CD10,CXCL13,和PD-1总结为60-100%的AITL 病例表达。同时,与上文一致,都认为这一点对ALTL与外周T和反应性增生的鉴别有意义。

老师您好,我对这篇文章很感兴趣,能把全文发给我吗?
根据淋巴结结构破坏程度和残留滤泡的多少将AILT分为三个形态学构象(pattern)。构象一:淋巴结结构部分破坏,淋巴滤泡容易辨认,但套区跟边界不太清晰,滤泡外不规则FDC网不明显;构象二:淋巴结丧失正常的结构,但可以看见散在的数量很少的淋巴滤泡,该种滤泡的FDC网比较集中。在有些病例中,可以看见延伸到滤泡外的FDC网;构象三:淋巴结结构完全破坏,没有可辨认的残留滤泡,不规则的FDC网明显可见。需要指出的是随着病情进展,会从构象一到构象三演进,因此也可以把三种构象看成的三种不同阶段的形态改变,同时三种构象之间就不可避免的存在重叠。
