There are 2 types of molar pregnancy: complete or partial. They are usually slow growing and benign, although there is a chance a mole can become cancerous. A complete molar pregnancy is much more likely to become cancerous than a partial molar pregnancy.
How rare is a partial molar pregnancy?
Partial molar pregnancy with a live fetus is a very rare condition, occurring in 0.005 to 0.01% of all pregnancies; it presents a challenging diagnosis, especially when clinical signs are almost completely absent.
Is a partial molar pregnancy a real baby?
In a partial molar pregnancy, there may be normal placental tissue along with abnormally forming placental tissue. There may also be formation of a fetus, but the fetus is not able to survive, and is usually miscarried early in the pregnancy.
Can a partial molar pregnancy be misdiagnosed?
Classic findings of molar pregnancy on TVUS are less frequently seen in early term and partial molar pregnancies. Missed incomplete molar pregnancies are often misdiagnosed as missed or incomplete abortions. Though rare, the presence of both molar pregnancy and a normal, viable co-twin can further hinder the diagnosis.
What happens after a partial molar pregnancy?
After a partial molar pregnancy
Once your hCG level is normal you give a further urine sample 4 weeks later. If your pathology has been reviewed at the hospital, your follow up is then complete. If the partial mole hasn’t been confirmed by the pathologists, you have follow up as for a complete molar pregnancy.
What are the chances of having two partial molar pregnancies?
The risk of having another molar pregnancy is only about 1 to 2 in 100 women (1 to 2 percent). If not treated, a molar pregnancy can be dangerous to the woman. It sometimes can cause a rare form of cancer. A molar pregnancy is a kind of gestational trophoblastic disease (also called GTD).
How long does a partial molar pregnancy last?
In a partial molar pregnancy, a fetus develops but it will be abnormal and cannot survive. At most, the fetus might survive for around three months.
How does a molar pregnancy become cancerous?
The cancer may also occur after a normal pregnancy. But it most often occurs with a complete hydatidiform mole. This is a growth that forms inside the womb at the beginning of a pregnancy. The abnormal tissue from the mole can continue to grow even after attempted removal, and can become cancerous.
How long does it take for hCG levels to drop after partial molar pregnancy?
In most women the levels of hCG drop fairly rapidly. Once your hormone level reaches zero for three weeks, follow-up will cease for those with a partial mole. For women with a complete mole, you will progress to monthly blood tests for a further six months.
Can a partial molar pregnancy have a heartbeat?
These include feeling nervous or tired, having a fast or irregular heartbeat, and sweating a lot. An uncomfortable feeling in the pelvis. Vaginal discharge of tissue that is shaped like grapes. This is usually a sign of molar pregnancy.
What are the symptoms of a partial molar pregnancy?
The most prominent symptom of a molar pregnancy is heavy bleeding from the vagina early in the pregnancy. The blood may be dark brown. Symptoms of a partial molar pregnancy include severe nausea, vomiting, and hypertension (high blood pressure) early in the pregnancy, often in the first trimester.
Is a molar pregnancy a tumor?
A molar pregnancy contains many cysts (sacs of fluid). It is usually benign (not cancer) but it may spread to nearby tissues (invasive mole). It may also become a malignant tumor called choriocarcinoma.
Can a molar pregnancy grow back?
After your molar pregnancy is removed, you’ll need more blood tests and monitoring. It’s very important to make sure that no molar tissue was left behind in your womb. In rare cases, molar tissue can regrow and cause some types of cancers.
What percent of molar pregnancies are cancerous?
Fewer than 15% of molar pregnancies become invasive and spread outside of the uterus. Choriocarcinoma. This is a cancerous tumor formed from trophoblast cells.
