The term "hydatidiform mole," also known as a molar pregnancy, refers to an abnormal growth of cells that can occur during pregnancy. Some synonyms for this condition include a "partial mole," "complete mole," or "gestational trophoblastic neoplasia." These terms are used to describe different types and stages of the disease. A partial mole refers to when the abnormal growth contains some fetal tissue, while a complete mole comprises only abnormal cells. Gestational trophoblastic neoplasia refers to when the abnormal growth persists after the pregnancy has ended and can lead to cancer in rare cases. Knowing these synonyms can help in discussing this condition with healthcare professionals.
