卵巢无性细胞瘤是一种比较罕见的恶性肿瘤。1925年 R.Meyer 氏认为该瘤系由于胚胎发育时期残留于性腺而未分化之种子细胞所形成,与未定性前之性细胞相似,其性质为中性,遂命名为无性细胞瘤。近年来文献报告,卵巢无性细胞瘤患者,有呈内分泌症状,病理检查则见肿瘤中混有颗粒细胞或类似睪丸间质细胞成分,可能为卵巢功能性肿瘤之一。目前国外文献报告约有450余例,国内自解放后已报告52例。我院附属医院及教学医院(省
Ovarian dysgerminoma is a relatively rare malignancy. In 1925, R. Meyer thought that the tumor was formed by undifferentiated seed cells that remained in the gonads during the embryonic development. Similar to the undenatured sex cells, it was of a neutral nature and was named as a dysgerminoma. In recent years, the literature reports that patients with ovarian dysgerminoma have endocrine symptoms, pathological examination showed that the tumor mixed with granulosa cells or similar stromal cell components, may be one of ovarian tumors. At present, there are about 450 cases reported in foreign literature and 52 cases have been reported since liberation in China. Affiliated Hospital of our hospital and teaching hospital (province
