Partial Molar Pregnancy With Normal Karyotype

Partial molar pregnancy results from fertilization of a haploid ovum by two sperms or duplication of one sperm, resulting in a triploid karyotype. The coexistence of partial mole with normal fetus karyotype is rare and occurs in 0.005-0.01% of all pregnancies. It is considered a challenging diagnosis. Here, we report a case of a 38-year-old primigravida diagnosed indecently at 16 weeks of gestation. She was on regular antenatal care and had partial molar pregnancy with a female fetus with diploid karyotype and no apparent malformation. This pregnancy ended with intrauterine fetal death. Histological examination of the placenta showed partial hydatidiform mole changes.
