What term describes the mass of grape-like vesicles formed in a Hydatidiform mole?

The mass of grape-like vesicles formed in a Hydatidiform mole is accurately described by the term "Clear vesicles." In the context of a Hydatidiform mole, which is an abnormal growth of tissue arising from a fertilized egg, the appearance of these vesicles is characteristic. They are formed from the trophoblastic tissue and have a distinct, fluid-filled structure that resembles grapes.

In this specific case, other terms like chorion and amnion refer to components of pregnancy but do not specifically convey the abnormal structure found in a Hydatidiform mole. The chorion is the outermost membrane surrounding the embryo and contributes to the formation of the placenta, while the amnion is the inner membrane that contains the amniotic fluid. Villi, which are finger-like projections found in a normal placenta, are not representative of the grape-like deformities seen in this type of molar pregnancy. Hence, "Clear vesicles" serves as the most accurate term to describe the unique mass formed in a Hydatidiform mole.
