Gestational trophoblastic diseases mainly include gravida pregnancy and gestational trophoblastic tumor, which is often called choriocarcinoma. Depending on the disease, there will be different clinical manifestations. The most common manifestations of gravidarum are an enlarged uterus, history of menopause, intermittent vaginal bleeding, and sometimes the discharge of grape-like tissue from the vagina. Trophoblastic tumor, which is also known as choriocarcinoma, will have luteinized ovarian cysts or metastatic manifestations, such as lung metastasis, vaginal metastasis, liver metastasis, brain metastasis, etc. After the appearance of metastasis, the above mentioned diseases suggest that they have already reached the stage of further development, and should be actively given appropriate treatment.
