2022年12月26日 · Molar pregnancies are also called hydatidiform moles. What are the types of molar pregnancies? Molar pregnancies fall into two categories: complete and partial. In complete molar pregnancies, no embryo forms. It happens when a sperm fertilizes an empty egg. Because the egg is empty, the embryo can’t grow.

Hydatidiform mole (HM) is a rare mass or growth that forms inside the womb (uterus) at the beginning of a pregnancy. It is a type of gestational trophoblastic disease (GTD). HM, or molar pregnancy, results from abnormal fertilization of the oocyte (egg). It results in an abnormal fetus.

A hydatidiform mole is a pregnancy/conceptus in which the placenta contains grapelike vesicles (small sacs) that are usually visible to the naked eye. The vesicles arise by distention of the chorionic villi by fluid.

2024年12月11日 · A hydatidiform mole, commonly referred to as a molar pregnancy, is a rare abnormality in pregnancy classified under gestational trophoblastic diseases (GTD), which stem from the placenta and may metastasize.

Most often, a molar pregnancy is an abnormal fertilized egg that develops into a hydatidiform mole rather than a fetus. A molar pregnancy may also develop from cells that remain in the uterus after a miscarriage , a full-term pregnancy, or a mislocated pregnancy ( ectopic pregnancy ).

2024年5月3日 · Hydatidiform mole (HM) was first described by Hippocrates around 400 BCE as "dropsy of the uterus." Since that time, HM (also referred to as molar pregnancy or mole) has been of clinical and research interest.

A hydatidiform mole (molar pregnancy) is a gestational trophoblastic disease. Ultrasonography is used to identify both complete and partial molar pregnancies. (See the image below.)...

2019年3月13日 · Hydatidiform mole is an abnormal pregnancy characterized by varying degrees of trophoblastic proliferation (both cytotrophoblast and syncytiotrophoblast) and vesicular swelling of placental villi associated with an absent or abnormal fetus/embryo.

2024年12月24日 · Hydatidiform mole, in human pregnancy, abnormal growth of the chorion, the outermost vascular membrane that in a normal pregnancy would enclose the embryo and ultimately give rise to the placenta. In the situation in which the hydatidiform mole develops, the embryo is usually either absent or dead.
