IT is important for women who experience a molar pregnancy to be tested for raised levels of the pregnancy hormone HCG (human chorionic gonadotrophin) because one in five to one in 10 women with a complete mole
and one in 200 with a partial mole can go on to develop cancer.
In about 20% of complete moles
and 2% of partial moles, there is some molar tissue left inside of the uterus, which can continue growing and lead to abnormal vaginal bleeding and risk of infection.
Cytogenetic analyses performed on G-bands with trypsin-Giemsa-banded chromosomes showed a 46,XY complete mole
and a normal 46,XX fetus.
The main differential diagnoses of PMD, both clinically and pathologically, are partial hydatidiform moles, a twin gestation with complete mole
, spontaneous abortion with hydropic changes, and confined placental mosaicism.
