tidiform mole | manifests by enlarged, edematous placental villi in a loose stroma (bunch of grapes) |
hydatidiform mole | causes a significant increase in hCG, characterized by vaginal bleeding and rapid increase in uterine size |
complete mole | no embryo present, 46xx karyotype of exclusively paternal derivation |
partial mole | embryo present, triploidy or tetraploidy, due to fertilization by two sperm |
gestational choriocarcinoma | aggressive malignant neoplasm, increased serum hCG, early hematogenous spred to lungs, is responsive to chemo |
gestational choriocarcinoma | is preceded by--> hydatidiform mole(50%), abortion of ectopic pregnancy(20%), normal term pregnancy (20-30%) |
