They can broadly be grouped as functional and neoplastic cysts.

他们可大致分为功能性囊肿和赘生性囊肿。

B cell lymphomas are more common and the neoplastic B cells usually express CD20 on their surface.

B细胞较为常见，肿细胞表面通常表达CD20。

And these are scattered among lots of neoplastic lymphocytes that look dark like the night sky.

它们分布在众多深色的肿细胞中，看起来就像夜空中。

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，包子宫内膜异位症囊肿、浆液性和黏液性囊腺、成熟囊性，以及恶性肿。

That's because there are a few " tingible bodies" which are macrophages that have eaten up dead neoplastic cells that look like little stars.

这是因为有一些着色小体巨噬细胞，也就是巨噬细胞，吞噬凋亡的肿细胞后，而看似像小星星。

Broadly speaking, neoplastic cysts are usually complex, meaning that they're larger than 10 centimeters, have irregular borders, and have internal septations creating a multilocular appearance.

一般来说，赘生性的囊肿比较复杂，大小会超过10厘米，边界不清；内部有隔断，形成多房状的外观。

Finally, the last category of neoplastic cysts include malignant ovarian tumours, like serous or mucinous cystadenocarcinomas, which develop from surface ovarian epithelium, just like their benign counterparts.

最后一种赘生性囊肿为卵巢恶性肿，如浆液或黏液囊腺癌，和良性的囊腺相似，它们也由表面的卵巢上皮形成。

Ok, now let's switch gears and look at ovarian tumors - since they also have cystic characteristics, they're also included under the umbrella term of neoplastic cysts.

好，接下来让我们看看卵巢肿：它们也有囊肿的特征，也是赘生性囊肿的一种。

When something like that happens, cells are supposed to undergo apoptosis - or programmed cell death, but instead the lymphocyte starts to divide uncontrollably - becoming a neoplastic cell.

当基因突变发生后，细胞本应经历凋亡，或称程序性细胞死亡；但相反，某些细胞开始不受控制地分裂，变成了肿细胞。

This form of lymphoma often involves the bone marrow, lymph nodes, and spleen, and the neoplastic cells sometimes produces immunoglobulins, called " M proteins, " that are found at high levels in the blood.

这种通常累及骨髓、结、脾，并且肿细胞可以产生免疫球蛋白，被称为“M蛋白”，他们（M蛋白）被发现在血中浓度增高。
