Which tumor is the most aggressive non-seminomatous germ cell tumor?

• A. Choriocarcinoma
• B. Embryonal Cell Carcinoma
• C. Teratoma
• D. Yolk Sac Tumor

Answer: (B)

Embryonal carcinoma carries primitive, undifferentiated cells that behave with high malignant potential. This stem-like, pluripotent biology drives rapid growth, easy invasion of surrounding tissue, and early spread to distant sites. Because of that aggressive behavior, it tends to be the most malignant among non-seminomatous germ cell tumors and often appears as part of mixed tumors, complicating treatment. Teratoma is more differentiated and tends to be less aggressive; yolk sac tumor and choriocarcinoma are also highly malignant, but the undifferentiated, aggressive nature of embryonal carcinoma makes it the most aggressive choice in this context.
