Hydatidiform mole stages, transfer and proliferation

Clinical staging of malignant Hydatidiform mole:
Stage Ⅰ: lesions confined to the uterus.
Stage Ⅱ: the spread of diseases from outside the uterus, but limited to genital mutilation.
Stage Ⅲ: disease spread to the lung.
Stage Ⅳ: disease spread to the whole body.

Transfer and proliferation of hydatidiform mole:
After the fall off villi of hydatidiform mole transfer to other parts of the body with the blood circulation, destruction of tissue, ranging from the size of hematoma formation, and another feature of malignant mole. This easy to use for the delineation of the characteristics of benign and malignant mole boundaries. As mentioned above, the normal pregnancy trophoblast epithelial cells can also enter the maternal blood circulation, and in other parts of the body was found, but it does not cause any destructive lesions, benign epithelial villi of hydatidiform mole can also be off of course with the blood supply to other parts of the body as if any of the migration of destructive inflammatory emboli and settlers, but can not afford to undermine the role of local. Therefore, we believe that the villi into the blood circulation does not result in damaging the host site belong to benign lesions, on the contrary is vicious. Should be clear that the chorionic villi of hydatidiform mole and normal pregnancy the trophoblast epithelium, although the same may enter blood circulation, but in biology and pathology characteristics or different. Both the role of the same non-local break, but the former more likely malignant. Malignant and malignant mole and should look at the difference. Although both transfer and tissues caused by the transfer of some degree of damage to properties, but the evil of the Portuguese metastasis may have its own regression, and malignant tumors, rarely subside on its own.
