Overview

A hydatid mole — also referred to as hydatid mole — may be a rare complication of pregnancy characterized by the abnormal growth of trophoblasts, the cells that normally become the placenta.

There are two sorts of hydatid mole , complete hydatid mole and partial hydatid mole . In a complete hydatid mole , the placental tissue is abnormal and swollen and appears to make fluid-filled cysts. There's also no formation of fetal tissue. In a partial hydatid mole , there could also be normal placental tissue along side abnormally forming placental tissue. There can also be formation of a fetus, but the fetus isn't ready to survive, and is typically miscarried early within the pregnancy.

A hydatid mole can have serious complications — including a rare sort of cancer — and requires early treatment.

Symptoms

A hydatid mole could seem sort of a normal pregnancy initially, but most molar pregnancies cause specific signs and symptoms, including:

Ø  Dark brown to bright red vaginal bleeding during the first trimester

Ø  Severe nausea and vomiting

Ø  Sometimes vaginal passage of grapelike cysts

Ø  Pelvic pressure or pain

If you experience any signs or symptoms of a hydatid mole , consult your doctor or pregnancy care provider. He or she may detect other signs of a hydatid mole , such as:

Ø     Rapid uterine growth — the uterus is too large for the stage of pregnancy

Ø     High blood pressure

Ø     Preeclampsia — a condition that causes high blood pressure and protein in the urine after 20 weeks of pregnancy

Ø     Ovarian cysts

Ø     Anemia

Ø     Overactive thyroid (hyperthyroidism)

Causes

A hydatid mole is caused by an abnormally embryo . Human cells normally contain 23 pairs of chromosomes. One chromosome in each pair comes from the daddy , the opposite from the mother.

In a complete hydatid mole , an empty egg is fertilized by one or two sperm, and every one of the genetic material is from the daddy . In this situation, the chromosomes from the mother's egg are lost or inactivated and therefore the father's chromosomes are duplicated.

In a partial or incomplete hydatid mole , the mother's chromosomes remain but the daddy provides two sets of chromosomes. As a result, the embryo has 69 chromosomes instead of 46. This most frequently occurs when two sperm fertilize an egg, leading to an additional copy of the father's genetic material.

Risk factors

Approximately 1 in every 1,000 pregnancies is diagnosed as a hydatid mole . Various factors are associated with molar pregnancy, including:

Ø    Maternal age. A hydatid mole is more likely in women older than age 35 or younger than age 20.

Ø    Previous molar pregnancy. If you've had one hydatid mole , you're more likely to possess another. A repeat hydatid mole happens, on the average , in 1 out of each 100 women.

Prevention

If you've had a hydatid mole , ask your doctor or pregnancy care provider before conceiving again. He or she may recommend expecting six months to at least one year before trying to become pregnant. The risk of recurrence is low, but above the danger for ladies with no previous history of hydatid mole.

During any subsequent pregnancies, your care provider may do early ultrasounds to watch your condition and offer reassurance of normal development. Your provider can also discuss prenatal genetic testing, which may be wont to diagnose a hydatid mole.
