Generally speaking, embryonal carcinoma, choriocarcinoma, endodermal sinus tumor, teratoma malignant transformation has a high degree of malignancy, and the degree of malignancy of mixed germ cell tumors depends on the composition of the cells in the tumors and the proportion of the components, while immature teratomas are relatively benign.
