Causes of hydatidiform mole are in the wrong set of chromosomes, duplication of the paternal and complete or partial absence of the parent. This anomaly happens if the defective fertilization of the egg occurs in two sperm. It’s defective egg with the wrong number of chromosomes or nuclear-free.

The first case gives the development of partial hydatidiform mole, the second case is complete. Patients suffering from cystic skid, the sperm and egg unite in the uterus, but fetal development never begins. Instead, in the uterus begin to form cysts, reminiscent of bubbles with a transparent liquid. Molar pregnancy usually develops within the uterus and has not spread to organs and tissues. Also the appearance of the disease is possible if the infection toxoplasmose, in violation of hormonal due to mutation of chromosomes.


There are several types of hydatidiform mole

  • full or simple view of the pathological changes in the chorion

The subsequent 8 weeks after surgery, observation is indicated obstetrician-gynecologist, a study of the level of beta-HCG in the blood and ultrasound once every two weeks. Chemical method is a system because all drugs enter the bloodstream of the body and spread to all organs and tissues, destroying the malignant cells detected. Chemotherapy can be conducted in the form of pills and intravenous and intramuscular injections.
