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，例如成熟的囊性畸胎瘤，又名皮样囊肿。

Think for example of a dermoid cyst, with its mixture of tissues like hair and sebaceous fluid: that's not something the peritoneal cavity is meant to handle!

试想以皮样囊肿为例，它含有毛发和脂状液体等的混合物，而那可不是腹腔能吸收的！
