卵巢无性細胞瘤系由一种在胚胎时期未分化的原始間叶細胞所形成,为原发性实質样恶性肿瘤。多見于幼女和年輕妇女,在1950年Mueller等氏分析世界文献的427例中,72％是发生于11——30岁之間;我国胡志远等氏1956年分析上海八大医院的13例中,最多是在16——20岁之間。是一种比較少見的疾患,占卵巢肿瘤总数的百分之一左右。关于本病起源,P.Pedowitz、Babes、及Schiler等諸氏,皆認为系由原始間叶的一种万能細胞中性发
Ovarian dysgerminoma is formed from a primitive mesenchymal cell that has not been differentiated during the embryonic stage and is a primary parenchymal malignancy. More common in young girls and young women, in 427 Mueller’s analysis of 427 cases of world literature, 72% occurred in the 11 - 30-year-old; China’s Hu Zhiyuan et al. In 1956 analyzed eight of the eight hospitals in Shanghai, It is between 16 and 20 years old. It is a relatively rare condition that accounts for about one percent of the total number of ovarian tumors. Regarding the origin of this disease, P.Pedowitz, Babes, and Schiler et al., all considered to be neutral cells of a universal cell derived from the primitive mesenchymal lobe.
