Benign mucinous tumors are called mucinous cystadenomas, and often develop on only one ovary.

良性黏液性肿瘤又被叫做黏液性囊腺瘤，通常只出现在一侧的卵巢内。

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

另一种是赘生性囊肿，包括子宫内膜异位症囊肿、浆液性和黏液性囊腺瘤、成熟囊性畸胎瘤，以及恶性肿瘤。

Some originate from surface ovarian epithelium, such as serous cystadenomas, which are often bilateral and filled with a watery fluid, and mucinous cystadenomas, which tend to be multilocular and contain a mucus-like fluid.

其中有些起源于卵巢上皮，例如卵巢浆液性囊腺瘤，常发病于双侧卵巢，充满水样液体；以及黏液性囊腺瘤，一般为多房，内含黏液。
