Partial hydatidiform mole.

A case of partial hydatidiform mole is presented, occurring in a young primiparous woman after natural conception. She presented with incomplete miscarriage. Histological diagnosis of partial mole was made. Failure of beta HCG to fall resulted in the start of chemotherapy. WHO scoring placed her in low risk group. In spite of the low risk, she required third line chemotherapy for complete eradication of disease.
