One rare complication that can cause particular heartbreak is molar pregnancy. Strange name, so what exactly is it? So instead of a viable pregnancy, you end up with an abnormal set of water-filled cysts. There are two types of molar pregnancy.
Most cases of persistent GTD are invasive moles, but in rare cases they are choriocarcinomas or placental site trophoblastic tumors see below. Invasive mole An invasive mole formerly known as chorioadenoma destruens is a hydatidiform mole that has grown into the muscle layer of the uterus.
Invasive moles can develop from either complete or partial moles, but complete moles become invasive much more often than do partial moles.
Invasive moles develop in less than 1 out of 5 women who have had a complete mole removed. The risk of developing an invasive mole in these women increases if: There is a long time more than 4 months between their last menstrual period and treatment.
The uterus has become very large.
The woman is older than 40 years. The woman has had gestational trophoblastic disease in the past. Invasive moles can sometimes go away on their own, but most often more treatment is needed.
A tumor or mole that grows completely through the wall of the uterus might result in bleeding into the abdominal or pelvic cavity. This bleeding can be life threatening.
Sometimes after removing a complete hydatidiform mole, the tumor spreads metastasizes to other parts of the body, most often the lungs. Choriocarcinoma Choriocarcinoma is a malignant form of gestational trophoblastic disease GTD.
It is much more likely than other types of GTD to grow quickly and spread to organs away from the uterus.
Half of all gestational choriocarcinomas start off as molar pregnancies. About one-quarter develop in women who have a miscarriage spontaneous abortionintentional abortion, or tubal pregnancy the fetus develops in the fallopian tube, rather than in the uterus.
Rarely, choriocarcinomas that are not related to pregnancy can develop. These can be found in areas other than the uterus, and can occur in both men and women. They may develop in the ovaries, testicles, chest, or abdomen. In these cases, choriocarcinoma is usually mixed with other types of cancer, forming a type of cancer called a mixed germ cell tumor.
These tumors are not considered to be gestational related to pregnancy and are not discussed in this document. Non-gestational choriocarcinoma can be less responsive to chemotherapy and may have a less favorable prognosis outlook than gestational choriocarcinoma.
For more information about these tumors, see Ovarian Cancer and Testicular Cancer.With a molar pregnancy, tissue in the uterus becomes an abnormal mass or tumor instead of a placenta. There are two types of molar pregnancy -- partial and complete. A partial one is when both the placenta and embryo (fertilized egg) are abnormal.
Molar Pregnancy: Symptoms, Risks and Treatment A molar pregnancy is an abnormality of the placenta, caused by a problem when the egg and sperm join together at fertilization.
Molar pregnancies are rare, occurring in 1 out of every 1, pregnancies. Nov 10, · Gestational trophoblastic disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. Learn more here. Molar pregnancy is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus and will fail to come to term.
A molar pregnancy is a gestational trophoblastic disease which grows into a mass in the uterus that has swollen chorionic initiativeblog.com villi grow in clusters that resemble grapes. A molar pregnancy can develop when a fertilized egg does not contain an.
a complete mole, where there's a mass of abnormal cells in the womb and no foetus develops a partial mole,where an abnormal foetus starts to form, but it can't survive or develop into a baby A molar pregnancy can usually be treated with a simple procedure to remove the growth of cells from the.
Pregnancy - Abnormal changes in pregnancy: An ectopic pregnancy is one in which the conceptus (the products of conception—i.e., the placenta, the membranes, and the embryo) implants or attaches itself in a place other than the normal location in the lining of the upper uterine cavity.
The site of implantation may be either at an abnormal location within the uterus itself or in an area.
