Pathologic assessment of the uterus in the index pregnancy after dilation and curettage. (A) For the elder sister, hematoxylin-eosin showed endometrial polyps and proliferative phase endometrium. The absence of fetal parts detected by curettage and laparoscopy might indicate a miscarriage of a hydatidiform mole or other deformed pregnancies. (B) For the younger sister, microscopic examination demonstrated generalized trophoblastic proliferation with hydropic degenerated villi, suggesting complete hydatidiform mole.
