宫颈上皮内瘤样病变(CIN)的诊断主要依据活体组织学检查,肉眼观察多呈糜烂及肥大状态。在妊娠期,子宫颈的某些上皮改变与CIN很相似,因此有必要了解妊娠期子宫颈的组织学变化特征,以便与CIN加以区别。妊娠时子宫颈组织学变化主要表现为三个方面。 1 子宫颈间质的改变妊娠期子宫颈间质内血管增多,组织水肿,并有炎性细胞浸润,使子宫颈体积增大,松软,甚至呈海绵状。约有1/3的孕妇子宫颈组织学检查见到有间质细胞蜕
Cervical intraepithelial neoplasia (CIN) diagnosis based mainly on biopsies, macroscopic observation of mostly erosion and hypertrophy. During pregnancy, certain epithelial changes in the cervix are similar to CIN, so it is important to understand the histological changes in the cervix during pregnancy in order to be differentiated from CIN. Cervical histology changes during pregnancy mainly in three aspects. 1 cervical interstitial changes during pregnancy, cervical interstitial blood vessels increased, tissue edema, and inflammatory cell infiltration, so that the cervical volume increased, soft, or even sponge-like. About 1/3 of pregnant women cervical tissue examination to see interstitial cell shedding
