Diagnosis
The diagnosis of a molar pregnancy might be suspected
based on a number of clinical features: abnormal vaginal
bleeding in early pregnancy is the most common
presentation; uterus large for dates (25%); pain from large
benign theca-lutein cysts (20%); vaginal passage of
grape-like vescicles (10%); exaggerated pregnancy
symptoms including hyperemesis (10%), hyperthyroidism
(5%), early preeclampsia (5%).
