We karyotyped a metastasis composed of pure yolk sac tumor derived from a primary ovarian germ cell tumor with two components: a dermoid cyst [DNA index (DI) 1.0] and a pure yolk sac tumor (DI 1.88). The metastatic yolk sac tumor had a hypertriploid karyotype and a DI of 1.78 and lacked the germ cell tumor marker i(12p). The absence of this marker in a metastasis from a tumor with a dermoid cyst component might be indicative for a pathogenesis of the yolk sac tumor similar to that of a dermoid cyst and different from that of dysgerminoma.
我们对一个转移灶进行了核型分析,该转移灶由源自原发性卵巢生殖细胞肿瘤的纯卵黄囊瘤组成,原发性肿瘤包含两个成分:一个皮样囊肿[DNA指数(DI)为1.0]和一个纯卵黄囊瘤(DI为1.88)。转移性卵黄囊瘤具有超三倍体核型,DI为1.78,并且缺乏生殖细胞肿瘤标志物i(12p)。在具有皮样囊肿成分的肿瘤转移灶中缺乏该标志物,可能表明卵黄囊瘤的发病机制与皮样囊肿相似,与无性细胞瘤不同。
