至今葡萄胎的诊断仍靠肉眼所见和组织病理.已知葡萄胎的本质不同,其组织学特征也各异.完全性葡萄胎是在孕体中无胎儿,而其绒毛间质中心积液呈囊状,并伴滋养叶增生和趋向穿透子宫壁.当部分绒毛增大足以证明为葡萄胎时则诊为过渡性葡萄胎.同样,病理的和非病理的卵所致的早期自然流产其绒毛均可并发囊性变,但非病理卵发生率低.从染色质的研究中得知完全性葡萄胎几均为女性.在六十年代中,应用染色体的检查来研究有囊性退变的自然流产,认识到孕体三倍体与绒毛肿胀
So far the diagnosis of hydatidiform mole still depends on the naked eye and histopathology.It is known that the different nature of hydatidiform mole and its histological features are different.The complete hydatidiform mole is without fetus in the pregnant body and its villus interstitial effusion Cystic, with trophoblastic follicular hyperplasia and tend to penetrate the uterine wall.When part of the villi increased enough to prove hydatidiform mole was diagnosed as a transitional mole.Moreover, the pathological and non-pathological eggs caused by early spontaneous abortion The villi can be complicated cystic degeneration, but the incidence of non-pathological eggs is low from the study of chromatin that complete hydatid almost all women.In the sixties, the use of chromosome examination to study the cystic back Become a spontaneous abortion, recognizing the triploid trimester and villus swelling
