摘要 目的探讨外周T细胞淋巴瘤临床和病理组织特征以及免疫组织化学特征在其诊断和鉴别诊断以及分类中的价值。方法应用组织形态学观察及免疫组织化学分析对既往诊断的64例外周T细胞淋巴瘤(PT-CLs),进行HE染色和CD45RO,CD20,CD3,CD56,CD4,CD8,CD30,ALK的免疫表型测定,结合临床,根据新的WHO2001分类标准进行分类和分析。结果确诊了64例外周T细胞淋巴瘤,包括29例外周T细胞淋巴瘤(非特殊性),占45.3%;13例间变性大细胞淋巴瘤(ALCL),占20.3%;11例(17.2%)结外NK/T细胞淋巴瘤(鼻型)(NK/TCL);肠病型T细胞淋巴瘤(ITCL)和皮下脂膜炎性T细胞淋巴瘤(SCPTCL)各5例,各占7.8%;1例侵袭性NK细胞白血病(ANKCL),占1.6%。临床上,男性多于女性,大于40岁多见(78%)。发生在淋巴结的有44例,其次鼻咽部10例,咽喉部5例,睾丸、腹部包块、左大腿、腰椎、甲状腺各1例,累及的部位较广。组织病理形态:瘤细胞大、中、小均可见,染色质细,胞浆浅染。免疫组织化学:64例外周T细胞淋巴瘤中70.3%,10.9%,98.4%分别表达CD45RO,CD20,CD3;13例间变性大细胞淋巴瘤中11例表达CD30,11例结外NK/T细胞淋巴瘤(鼻型)100%表达CD56,阳性率和阴性率差异有显著性。结论外周T细胞淋巴瘤是一类异质性很强的肿瘤,必须结合临床、病理组织特征和免疫组织化学特征进行诊断和鉴别诊断以及分类。
