Immature teratomas tend to be malignant and metastasize quickly.

未成熟胎瘤有恶性倾，转移很快。

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

有的起源于卵巢生殖细胞，例如成熟的囊性胎瘤，又名皮样囊。

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

第一种是胎瘤，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.

二种是未成熟胎瘤，专门由神经外胚层细胞发育而来，来自外胚层。

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

哦，哦，胎瘤，里面有毛细胞，啊，我不能，我不知道。

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

另一种是赘生性囊，子宫内膜异位症囊、浆液性和黏液性囊腺瘤、成熟囊性胎瘤，以及恶性瘤。

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生殖细胞分化而来。

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：胎瘤，成熟囊性胎瘤和未成熟胎瘤；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。

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.

所以胎瘤就像怪物瘤，因为它像形胎儿一样拥有各种人体组织，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。

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.

第1种是成熟的囊性胎瘤，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。
