Complete mole Paial mole No fetal tissue Fetal tissue present in a paial mole 90% are 46, XX, and 10% are 46, XY. All chromosomes are of paternal origin 69, XXX most common , or 69, XXY An Empty oocyte is feilized by a haploid sperm (which then duplicates its chromosomes), or, an empty oocyte is feilized by 2 sperms This results from feilization of a haploid ovum by 2 sperms, both carrying X chromosome mostly Diffuse swelling of Chorionic villi Scalloping not seen Paial Swelling of chorionic villi Scalloping of villi seen There is diffuse trophoblastic hyperplasia Focal hyperplasia of trophoblastic tissue
