摘要 目的探讨子宫内膜样癌伴性索样结构和玻璃样变的临床病理学特征。方法收集2016年12月~2020年12月浙江大学医学院附属妇产科医院收治的3例子宫内膜样癌伴性索样结构和玻璃样变的临床病理学资料,行免疫组化EnVision两步法染色,总结其临床病理学特点。结果3例患者均为女性,发病年龄37~59岁,平均48.3岁,3例均为FIGOⅠA期。3例均含有典型的子宫内膜样癌形态结构伴有鳞状分化,肿瘤组织学分级Ⅰ级2例、Ⅱ级1例。另外,10%~50%区域可见性索样结构和玻璃样变的组织成分。免疫表型:性索样区CK(局灶+),β-catenin(核+),2例ER、PR均(-),1例ER、PR(散在+),EMA、CD10、inhibin、SMA、CgA、Syn均(-),Ki-67增殖指数2%~5%。网状纤维染色显示性索样区呈巢团状分布。3例患者随访时间5~51个月(平均22.3个月),均无复发。结论子宫内膜样癌伴性索样结构和玻璃样变具有其独特的病理形态学特点及相对较好的预后,其可能来源于上皮-间质转化,但分子机制尚不完全清楚。
