Trophoblastic Disease(Hydatidiform Mole)


What is Trophoblastic Disease?

Trophoblastic Disease (also called a Hydatidiform Mole) is when the layer of cells that line the gestational sac convert to a mass of clear vesicles instead of a healthy placenta. Without the placenta, the fertilized egg deteriorates. It is believed that this is caused by a chromosomal abnormality in the fertilized egg. Roughly 1 in 2,000 pregnancies in the USA are affected, and it occurs more frequently in women over 45 years old than in younger women.

The first sign is usually an intermittent or continuous browninsh discharge.
