Some originate from ovarian germ cells, such as mature cystic teratomas, also called dermoid cysts.

有的起源于卵巢细胞，例如成熟的囊性畸胎瘤，又名皮样囊。

The first, are teratomas, terato means monster and oma is a tumor.

一种是畸胎瘤，terat-的意思是怪物，-oma是瘤。

The other type are immature teratomas, and they develop specifically from neuroectoderm cells - which come from the ectoderm layer.

二种是未成熟畸胎瘤，专门由神经胚层细胞发育而来，来自胚层。

Immature teratomas tend to be malignant and metastasize quickly.

未成熟畸胎瘤有恶性倾向，并且转移很快。

On the other hand, neoplastic cysts include endometriomas, serous and mucinous cystadenomas, and mature cystic teratomas, as well as malignant ovarian tumors.

另一种是赘性囊，包括子宫内膜异位症囊、性和黏性囊腺瘤、成熟囊性畸胎瘤，以及恶性瘤。

Oh, oh a teratoma, that has hair cells in, ah, I can't, I have no idea.

哦，哦，畸胎瘤，里面有毛细胞，啊，我不能，我不知道。

Mature cystic teratomas are the most common ovarian tumors in young women and usually contain a heterogeneous mix of mature tissues that come from two or three of the germ cell layers.

成熟囊性畸胎瘤是年轻女性中最常见的卵巢瘤，内容物常为多种成熟组织的混合物，分别由两个或三个胚层的细胞分化而来。

So teratomas are monster tumors, and they are called that because they contain all different types of tissues, including hair, eyes, teeth, bone and neurons - kind of like a Frankenstein that's got bits of this and that stitched together.

所以畸胎瘤就像怪物瘤，因为它像畸形胎儿一样拥有各种人体组织，包括头发、眼睛、牙齿、骨骼和神经组织，有点像科学怪人一样把各类组织缝在了一起。

The four major types of germ cell tumors are: fetal teratomas, both mature cystic and immature teratomas; yolk sac tumors, or endodermal sinus tumor, choriocarcinoma or placental tissue tumors and finally dysgerminomas or oocyte tumors.

4种卵巢细胞癌如下：畸胎瘤，包括成熟囊性畸胎瘤和未成熟畸胎瘤；卵黄囊瘤，又叫内胚窦瘤；绒毛膜癌，又叫胎盘组织瘤；最后是无性细胞瘤，又叫卵母细胞瘤。

Now, there are two types of teratomas, the first are mature cystic teratomas, which are the most common ovarian tumors in young women and are formed from tissue that comes from any of the three germ layers.

1种是成熟的囊性畸胎瘤，是年轻女性中最常见的卵巢瘤，由三胚层中的任一层组织形成。
