摘要 目的:探讨子宫内膜上皮内瘤变(EIN)的临床病理特征、免疫表型、诊断与鉴别诊断。方法:对23例子宫内膜上皮内瘤变进行光镜观察(视野直径>1 mm)、免疫组化研究及部分病例随访。结果:23例诊刮子宫内膜组织标本,镜下观子宫内膜腺体增生拥挤且不规则,增生腺体分布区域大于间质分布区域(局灶性或弥漫性分布)。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。23例均做抑癌基因(PTEN),肿瘤抑制基因(p53),雌激素受体(ER),孕激素受体(PR)检测,60.9%(14/23)PTEN(-),8.7%(2/23)p53(+),43.5%(10/23)ER,PR(+)。5例随访病例中2例发现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,更易于组织病理诊断标准趋向一致。
