Chorea: Ceaseless rapid complex body movements that look well coordinated and purposeful but are, in fact, involuntary.
Chorea was thought suggestive of a grotesque dance. The term “chorea” is derived from the Greek word “choreia” for dancing (as is choreography).

- Chorioamnionitis
Chorioamnionitis: Inflammation of the chorion and the amnion, the membranes that surround the fetus. Chorioamnionitis usually is associated with a bacterial infection. This may be due to bacteria ascending from the mother’s genital tract into the uterus to infect the membranes and the amniotic fluid. Chorioamnionitis is dangerous to the mother and child.
- Chorioangioma, placental
Chorioangioma, placental: A benign tumor of a blood vessel in the placenta. Large chorioangiomas can cause complications, including excess amniotic fluid (polyhydramnios), maternal and fetal clotting problems (coagulopathies), premature delivery, toxemia, fetal heart failure, and hydrops (excess fluid) affecting the fetus. Chorioangiomas probably act as shunts between arteries and veins (arteriovenous shunts), leading to progressive […]
- Choriocarcinoma
Choriocarcinoma: A highly malignant tumor that arises from trophoblastic cells within the uterus. Choriocarcinoma tends to be invasive and to metastasize early and widely through both the venous and lymphatic systems. Choriocarcinoma is one of the two types of gestational trophoblastic tumor, the other being hydatidiform mole. Choriocarcinoma may follow any type of pregnancy. It […]
- Chorion
Chorion: The outermost of the two fetal membranes (the amnion is the innermost) that surround the embryo. The chorion develops villi (vascular finger-like projections) and develops into the placenta.
- Chorionic villus sampling
A procedure for first-trimester prenatal diagnosis. Abbreviated CVS. CVS may be done between the eighth and tenth weeks of pregnancy. The aim is to diagnose severe abnormalities that are present in the fetus. Tissue is withdrawn from the villi of the chorion, a part of the placenta, and then prepared for diagnostic analysis.
