Abstract

Introduction: preeclampsia is one of the rare symptoms of molar pregnancy and is more prevalent in pregnancies with large volumes of abnormal trophoblastic tissue. Preeclampsia is associated with hypertension and proteinuria and rarely occurs in patients with Hydatidiform mole. Since in most cases, molar pregnancy is diagnosed by sonography at first trimester of pregnancy, the possibility of gestational trophoblastic disease should be considered in all patients with preeclampsia in first trimester of pregnancy. The aim of this report is to introduce a case of hydatidiform molar pregnancy with preeclampsia in 6th weeks of pregnancy.
Case report: A 15-year-old primigravid female with 6 weeks of menstrual retardation and diagnosis of molar pregnancy with increase of β-HCG titers, proteinuria and upper extremity edema was referred to emergency of maternity ward of an academic hospital, Mashhad University of Medical Sciences in 2017. Preeclampsia was confirmed. After curettage, hydatidiform mole was diagnosed. Preeclampsia associated with molar pregnancy was diagnosed. After mole curettage, blood pressure reached to normal and edema and other symptoms were gradually improved.
Conclusion: Preeclampsia is one of the rare symptoms in molar pregnancy. Considering that in most cases molar pregnancy is diagnosed with ultrasound in the first trimester of pregnancy, it is recommended that hydatidiform mole should be considered in all patients with preeclampsia in early pregnancy.
