摘要 目的:探讨子宫内膜上皮内瘤变(EIN)临床病理特征、免疫表型、诊断与鉴别诊断。方法:对40例子宫内膜上皮内瘤变进行光镜观察(视野直径>1mm),免疫组化研究及部分病例随访。结果:40例诊刮子宫内膜组织标本,镜下子宫内膜腺体增生拥挤,且有些不规则,增生腺体分布区域大于间质分布区域,腺上皮细胞多具有非典型性,表现为核大、核浆比大,核变圆、有明显的核仁,核染色质粗颗粒状、分布不均。40例均作PTEN、p53检测,65%(26/40)PTEN(-),5%(2/40)p53(+)。9例随访病例中2例发现同时存在子宫内膜样腺癌。结论:在子宫内膜癌前病变诊断标准上强调子宫内膜组织结构的异常改变,在诊断中可重复性较好,使组织病理诊断标准更趋向一致。
