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。

The malignant type of serous tumors are called serous cystadenocarcinomas, and malignant mucinous tumors are called mucinous cystadenocarcinomas.

恶性浆液性肿瘤被称为浆液性囊腺癌，而恶性黏液性肿瘤也称黏液性囊腺癌。

Mucinous tumors, on the other hand, have mucus-filled cysts that often involve large multiloculated cysts, but can also be benign, malignant, or borderline.

黏液性肿瘤，从另一个方面来说，有着充满黏液的囊泡，总是包含大而多腔的囊肿，但它也可以是良性、恶性或者中性的。

Serous and mucinous tumors arise from epithelial cells that line the outside of ovaries, whereas even though the tumors are found in the epithelium, the endometrioid and transitional cell tumors arise from other cell types.

浆液性和黏液性肿瘤是由卵巢外侧上皮细胞癌变引起的，而虽然这两种癌症都来自上皮的癌变，内膜样和移行性肿瘤却来自其他类型的细胞。
