Molar pregnancy symptoms and diagnosis
Molar pregnancy is the abnormal form of pregnancy which results in the presence of a hydatid mole. The mole consists of cellular growth which contains nonviable embryo implanted to uterus wall and also proliferates in the uterus. Bleeding in the genital tract at fifth or sixth month of pregnancy is the main symptom of molar pregnancy. Early diagnosis and removal of molar pregnancy is needed to prevent complications such as choriocarcinoma, a type of cancer. One mother out of 1000 pregnancies may report molar pregnancy. Partial molar pregnancy is also one form of molar pregnancy.
Maternal chromosomes are absent in the fertilized embryo of molar pregnancy. While in normal pregnancy 23 pairs of chromosomes are present in the zygote.
Normal number of chromosomes from the mother and duplicate form of doubled chromosomes from father are found in case of partial molar pregnancy. So the total number of chromosomes in case of partial molar pregnancy is 69 instead of 46 chromosomes. In case of complete molar pregnancy the inviable fetus is present. But in case of Partial molar pregnancy some fetal tissue is present. The fetus of partial molar pregnancy has genetical abnormality and the survival rate of fetus is very less.

* The mole is found like a bunch of grapes with a cluster,
* Enlarged chorionic villi is also observed during diagnosis.
* Hyperthyroidism is also seen in some cases.
Treatment of molar pregnancy:-
- Evacuation of uterus by uterine suction is used to treat hydatidiform of moles.
- Surgical curettage is done soon after the diagnosis of Molar pregnancy.
- Preventing the development of choriocarcinoma is the main aspect of treatment.
- Patient is checked for decreased or nil level of chorionic gonodotrophin hormone level, which confirms the effective treatment of molar pregnancy.
- Metastatic pregnancy moles are treated with Chemotherapy, and the medicine Methotrexate is also administered to treat cancer type pregnant moles in the uterus.
Patient of molar pregnancy who undergoes treatment are advised not to get conceived till 12 months after treatment.
