补充资料:子宫内膜上皮内瘤样病变
子宫内膜上皮内瘤样病变
EIN包括子宫内膜不同程度的不典型增生和原位癌。以前称之为子宫内膜不典型增生过长、腺瘤型增生过长、不典型腺瘤型增生过长、重度增生过长、腺型增生过长有细胞不典型及原位癌等。EIN的组织形态:腺细胞呈复层,排列失去极性,较大而不规则,有大而不规则的核仁、局部细胞质多而呈伊红色。病灶多为局部、多发性,可与正常、萎缩或各型增生过长相间存在。目前EIN名称尚未被广泛应用,仍多用子宫内膜不典型增生。至于子宫内膜原位癌的诊断至今尚无统一的定义。近年部分病理学家意见:“一个真正的内膜原位癌是腺体已有肿瘤性变化而无间质浸润。”而实际上在诊断时要肯定这样的病变相当困难。一般临床遇到EIN中至重度时,故其癌前病变常采用手术治疗,切除子宫。
