Hydatidiform mole

Alternative names:

hydatid mole

Treatment:

If spontaneous abortion does not occur and the diagnosis is confirmed, therapeutic abortion is performed by suction curettage. Following either case, serum HCG levels are monitored to assure they return to a normal, non-pregnant level. A hysterectomy may be an option for older women who do not desire future pregnancies.

Expectations (prognosis):

More than 80% of hydatidiform moles are benign. Outcome after treatment is usually excellent. Close follow-up is essential. Highly effective means of contraception are recommended to avoid pregnancy for at least 1 year.

In 10 to 15% of cases, hydatidiform moles may develop into invasive moles. Invasive moles, however, may intrude so far into the uterine wall that hemorrhage or other complications develop.

In 2 to 3% of cases, hydatidiform moles may develop into choriocarcinoma, which is a malignant, rapidly- growing, and metastatic (spreading) form of cancer. Despite these factors, the rate of cure is high. Over 90% of women with malignant, non-spreading (nonmetastatic) disease are able to preserve reproductive abilities. In those with metastatic disease, remission remains at 75 to 85%.

Complications:

Acute pulmonary (lung) insufficiency may develop after evacuation of the uterus in cases where uterine enlargement is greater than 16 weeks gestational size.

Calling your health care provider:

Call your health care provider/obstetrician if hydatidiform mole is suspected.
