摘要
目的：研究早期子宫内膜腺癌及其癌前病变（腺瘤型增生及非典型增生）的超微结构，为早期鉴别诊断提供依据。方法：对８例子宫内膜腺瘤型增生，６例非典型增生，１２例Ⅰａ期子宫内膜高分化腺癌进行了扫描电镜及透射电镜检查。结果：腺瘤型增生细胞表面的纤毛、微绒毛明显增加，基膜完整，胞浆内初级溶酶体增加，细胞核异型性不明显。高分化腺癌细胞表面的纤毛、微绒毛明显减少且形态异常，基膜不完整，胞浆内初级溶酶体减少，次级溶酶体增多，粗面内质网和线粒体的形态及排列异常，细胞核异型性较明显，有的瘤细胞核内见核小体及核包涵体。非典型增生细胞表面及胞浆内的超微结构与高分化腺癌相似，但基膜基本完整，核内未见核小体及核包涵体。结论：诊断和鉴别早期子宫内膜腺癌及其癌前病变，电镜比光镜更有价值。
