2、由中等至较大的肿瘤细胞组成,核圆形或多角形,核仁明显。Ⅱ型EATL瘤细胞形态单一,体积中等或偏小,核圆形、深染,核碎屑和坏死常见。两种类型EATL背景中均可见组织细胞和中性粒细胞等炎症细胞,且肿瘤细胞弥漫表达CD3、CD43、T1A1,不表达CD4、CD5、CD20、CD79a。lI型EATL弥漫表达CD56和CD8,I型EATL不表达CD56和CD8,Ki-67增殖指数均>70%,EBERs原位杂交阴性。7例获得随访资料,其中4例患者术后10个月内死亡,3例患者术后18个月内死亡。结论EATL是一种罕见的源于肠道上皮内T淋巴细胞的侵袭性淋巴瘤,临床主要表现为长期慢性腹泻、腹痛
3、、发热及腹部包块等症状,部分病例可发生肠穿孔。诊断时需结合临床表现、病理检查及免疫表型。关键词:淋巴瘤;肠病相关性T细胞淋巴瘤;胃肠道淋巴瘤;CD56;CD8;免疫组织化学中图分类号:R733.4文献标志码:A文章编号:1001—7399(2015)06—0624—04doi:10.13315/j.cnki.cjcep.2015.06.006Enteropathy-associatedT-celllymphoma:aclinicopathologicalanalysisofninecasesHUYue—ming,ZHANGZhi—yong,LIULi—yun,XUJin—hen
