Embryonic Molar Pregnancy: A Rare Case Report

Partial hydatiform mole (MHP) represents a spectrum of trophoblastic-related disorders occurring during pregnancy. Also known as embryonal mole, it is characterized by a recognizable ovum abnormality with vesicular transformation of villi but with recognizable placental appearance and amniotic cavity containing the fetus. First-trimester spontaneous abortion most commonly suggests the diagnosis. Partial moles rarely persist beyond the first trimester and are then a cause of maternal and fetal complications and diagnostic confusion. MHP of genetic origin is triploi d with extra chromosome of paternal origin. The coexistence of normal fetal karyotype and MHP is exceptional. We report a rare case of partial molar pregnancy with liveborn diploid fetus in a 30-year-old woman diagnosed with threat of premature labour associated with placenta previa at 11 weeks of amenorrhea (WA).
