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