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.
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.
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 ...
Causes of melanoma. Ultraviolet light exposure from the sun or from tanning beds causes most melanomas. Melanoma may appear at a spot where you have an existing mole. But if an unusual spot shows ...

Common characteristic manifestations of gestational choriocarcinoma include irregular vaginal bleeding and hydatidiform moles. A hydatidiform mole is a red hemorrhagic mass with various sizes in the uterus. [14] Often, diagnosis is presumptive.

Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
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.
