What should you know about molar pregnancy placenta?

The placenta normally forms a connection between the pregnancy and the uterus, allowing exchange of oxygen and nutrients. In a molar pregnancy, the cells that would contribute to placental tissue multiply in an abnormal pattern. A complete mole has no normal embryo, while a partial mole may contain some fetal tissue that cannot develop normally.

The tissue may appear swollen or made up of many small cyst-like spaces. That appearance can be seen on ultrasound or after removal, but the laboratory examination gives the clearest classification. The abnormal cells also produce pregnancy hormone, which is why serial blood testing is part of follow-up.

Care usually involves removing the molar tissue from the uterus, followed by planned blood tests until the pregnancy hormone has cleared. Use the follow-up schedule provided by the specialist, even if bleeding and other symptoms improve. Tell the team about medicines, future pregnancy plans, and any new symptoms.

If hormone results plateau or rise, the specialist may investigate persistent gestational trophoblastic disease. Chemotherapy is one possible treatment for persistent or spreading disease, and the choice depends on the type and extent of the condition.

Seek urgent help for heavy vaginal bleeding, dizziness or fainting, severe abdominal pain, chest symptoms, or difficulty breathing. Bleeding between periods is not specific to a molar pregnancy, but bleeding connected with a suspected or confirmed pregnancy should be assessed without delay.

Ask whether the tissue is a complete or partial mole, what the laboratory report means, how often hormone tests are needed, which contraception advice applies during monitoring, and what treatment would be offered if results do not fall as expected.
