性腺的组织发生与卵巢肿瘤的分类

Histogenesis of Gonads and Classification of Ovarian Tumours

本文观察了胚胎发育与性腺的组织发生,并以此作为研究卵巢肿瘤病理的基础。选择了宫外孕,人工流产,剖腹产和新生儿死婴共9例,按不同受精胚龄或胎龄的胚胎或胎儿发育,分别寻找性腺,从未分化性腺、男女性腺的各阶段的发育特征,进一步认识卵巢肿瘤分类的多样性和多类型性。根据性腺的形成基础可将卵巢肿瘤分为上皮性,性腺间质性、生殖细胞性、非特殊间质性和转移性5大类。

Embryonal development and histogenesis of gonads were investigated in this study, which were considered as the base for studying pathology of ovarian tumours.Nine cases were collected from ectopic pregnancy, induced abortion, parturition caesareus and newborn death. In different stages of embryo and faetus, gonads were found out. Based on development characters in undifferentiated gonads and various periods of female or male gonads, the varieties and multiplicities of ovarian tumours were further recognized. Ovarian tumours may be classified into epithelial, gonad stromal, germ cellullar non-specialized stromal and metastatic ones.
