TWO CASES OF HYDATIDIFORM DEGENERATION OF THE PLACENTA WITH FETAL ABNORMALITY AND TRIPLOID CHROMOSOME CONSTITUTION

Abstract

Summary Triploidy is a fairly common cause of abortion in the first trimester. It is uncommon for such a pregnancy to continue beyond this time. Two cases of triploidy with hydatidiform degeneration of the placenta and fetal abnormality where the pregnancies continued to 29 and 25 weeks are reported. The concentration of HCG in these abnormal placentae was high and the patients excreted larger than normal amounts of it. Severe pre‐eclampsia and anaemia occurred. Other cases in the literature are reviewed.
