子宫腺癌包括子宫内膜和宫颈腺癌,子宫内膜腺癌最常见的是子宫内膜样腺癌,其次是浆液性癌,尽管浆液性癌可根据其典型的形态学特征(乳头状结构和高级别核)和免疫表型(p53弥漫/强阳性、激素受体失表达)而能与子宫内膜样腺癌区分,但子宫浆液性癌腺样亚型形态学非常类似于FIGO分级2 Uterine adenocarcinomas include endometrial and cervical adenocarcinomas, and endometrial adenocarcinomas are the most common endometrioid adenocarcinomas, followed by serous carcinomas, although serous carcinomas can be characterized by their typical morphological features (papillary structures And high-grade nuclear), and immunophenotype (diffuse / strong p53, loss of hormone receptor expression) but differentiated from endometrioid adenocarcinoma, but the morphology of uterine serous adenoid-like subtypes is very similar to that of FIGO grade 2
