Point of distinction between paial mole to complete mole is:
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
Paial mole show trophoblastic proliferation with absent villi
Typical of paial mole is diffuse cellular atypia
Paial mole is more prone to tumor malignancy
Paial mole is triploid
