IntroductionA partial mole occurs when a normal egg is fertilized by one or two sperm which then reduplicates itself, resulting in a triploid or tetraploid karyotype in the fetus. Partial molar pregnancy is an irregular pregnancy in which the embryo either grows incompletely, or doesn’t grow at all which mostly ends in a miscarriage. Inside the uterus multiple cysts grow which are known as hydatidiform mole. Hydatidiform Mole (HM) is the most frequent form of Gestational Trophoblastic Disease (GTD). Symptoms associated with partial molar pregnancy are frequent bleeding from the vagina in early pregnancy during the 1st trimester. Other symptoms may include severe vomiting and nausea, high blood pressure. Partial molar pregnancy is diagnosed by performing an ultrasound which reveals presence of cysts in the uterus especially placenta, low amniotic fluid and less developed fetus. A test is carried out that measures the levels of beta human chorionic gonadotropin (HCG). β-HCG is a hormone that is released in women while they’re pregnant. It appears in the blood or urine a week after the egg has been fertilized. In partial molar pregnancy the levels of β-HCG increase less rapidly than in a normal pregnancy. This case report is about a women who was pregnant with a hydatidiform partial mole and a coexisting live fetus. A twin pregnancy with one fetus and a coexistent mole, used to be an unusual occurrence but in recent times it is more frequent possibly due to the rise in ovulation induction. In every 22 000–100 000 pregnancies 1 case is of a pregnancy with hydatidiform mole[1], most pregnancies are complete hydatidiform moles (CHM) with a fetus. The told incidence for a partial mole with a coexisting fetus is 0.005–0.01% of pregnancies [2].
