Specifically, the chorionic villi in these placentas show varying degrees of trophoblastic proliferation and edema of the villous stroma.They areof two types: partial and complete.Complete MolePartial mole* A molar pregnancy with some normal and some swollen villi plus fetal, cord, and/or amniotic membrane elements.* Fetal tissue present.* Karyotype: 46, XX or 46, XY* Villous edema: diffuse* Typical clinical presentation: Molar gestation* Postmolar malignant sequelae-15-20%* A molar pregnancy with swelling of all placental villi.* Fetal tissues are absent.* Karyotype: 69, XXX or 69, XXY* Villous edema: focal* Typical clinical presentation: Missed abortion* Postmolar malignant sequelae- 2-4%Investigation* Diagnosing in first-trimester is now common because of the routine use of serum (3-hCG measurements (as they produce excess (3-hCG due to trophoblastic proliferation) and transvaginal sonography.* Although (3-hCG levels are helpful, the diagnosis of molar pregnancy more frequently is found sonographically because of the identifiable diffuse swelling and enlargement of the chorionic villi.* Appearance on USG: Snow storm appearnceTreatment* Suction curettage is the preferred method of evacuation regardless of uterine size in patients who wish to remain fertile.POSTMOLAR SURVEILLANCE* Gestational trophoblastic neoplasia (GTN) develops after approximately 15-20 % of complete moles and 2-4% in partial moles.* Postmolar surveillance with serial quantitative serum b-hCG levels is the standard.Also Know* GTD INCLUDES: H.Mole, Invasive mole, ChorioCA, PSTT (Placental Site Trophoblastic Tumor)* MC site of metastasis of GTD: Lungs
