False about partial mole a. Caused by triploidy b. Can be diagnosed very early by USG c. Can present as missed abortion d. Rarely causes persistent GTD

Patients with partial mole do not have dramatic clinical features of complete molar pregnancy. In general these patients have signs and symptoms of incomplete or missed abortion and on USG after they are confused with incomplete abortion. Partial mole can cause GTN in 3–5% cases Thus both, option d and b are incorrect, you can choose between the two. Presence of focal cystic spaces in the placental tissue and increase in the transverse diameter of the gestational sac has a positive predictive value of 90% for the diagnosis of partial mole.
