● Failure of development or early embryonic demise with persistent trophoblast development, leading to an anembryonic gestation
● Villous stromal edema without central cistern formation or trophoblastic hyperplasia
● Features of karyotypic abnormalities may be present
● 52% are trisomic (smaller villi without cisterns), 20% are triploid (resemble partial moles with focal trophoblastic invaginations, cisterns, irregular surfaces and dysmorphic features) and 15% are XO and 6% are tetraploid
● Before week 8, aneuploidy is most common with embryonic growth disorganization
