Vesicular or hydatiform mola, what it is

La vesicular or hydatiform mola it is an abnormal mass of cells that can grow inside the uterus in early pregnancy. In practice it is an anomalous product of conception, characterized by pathological proliferation of the trophoblast, the tissue that forms the outline of the placenta. In this condition the chorionic villi are altered and transformed into cysts, that is vesicles (hence the name of the disease). There molar pregnancy could be:





  • Assessment, if no fetus develops;
  • incomplete, if an abnormal fetus begins to develop but cannot survive anyway.

Frequency

The vesicular mola is one rare condition, which affects one pregnancy every 1000-1500. Molar pregnancy is more common for women over 40 and under 20, i.e. at the extremes of reproductive age.

How is the diagnosis made

Transvaginal ultrasound examination and beta-hCG measurement are essential for diagnosis. In the presence of a vesicular mola, the beta-hCG values ​​are higher than normal. 



How we intervene

The treatment involves the emptying of the uterine cavity from the molar material, on which it is necessary to perform histological examination.

Subsequent checks

After a molar pregnancy, it is essential to carry out serial sampling of beta-hCG, to promptly diagnose any persistence of the degenerated tissue in the uterus. If the beta value gradually decreases until it returns to normal (which happens in most cases), no further treatment is required.
