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。

Benign serous tumors are called serous cystadenomas, and are the most common type, and often develop on both ovaries, and typically affect premenopausal women.

良性浆液性肿瘤被称作浆液性囊腺瘤，同时也是最常见的，通常出现在两侧卵巢内，而且常见于绝经前的女性。

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。
