In partial moles, some villi are vesicular, whereas others appear more normal, and embryonic/fetal development may be seen but the fetus is always malformed and is never viable. Uterus with complete hydatidiform mole. In rare cases, a hydatidiform mole co-exists in the uterus with a normal, viable fetus. These cases are due to twinning. The ...
Invasive hydatidiform mole is a type of neoplasia that grows into the muscular wall of the uterus. It is formed after conception ( fertilization of an egg by a sperm ). It may spread to other parts of the body, such as the vagina , vulva , and lung .
Epidemiological studies have reported that hydatidiform mole appears to be caused by abnormal gametogenesis and fertilization more frequent at the extremes of reproductive age of younger than 15 and older than 45 years of age and pregnancies at these ages are a risk factor for hydatidiform mole.
Since gestational choriocarcinoma (which arises from a hydatidiform mole) contains paternal DNA (and thus paternal antigens), it is exquisitely sensitive to chemotherapy. The cure rate, even for metastatic gestational choriocarcinoma, is more than 90% when using chemotherapy for invasive mole and choriocarcinoma.
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.

One guideline for biopsy is if a growth is present three months after surgery, if a growth is greater than two centimeters, or if a growth is becoming larger one month after vaccination.
