Testicular mixed germ cell tumors are, as the name suggests, testicular tumors composed of two or more types of germ cell tumor. They are considered to be part of non-seminomatous germ cell tumors, as it is that component which dictates prognosis and treatment.
Overall they account for over 10% of all testicular cancers (15% of all testicular germ cell tumors which account for 90% of all testicular cancers) 1.
Epidemiology, clinical presentation, and radiographic features will correspond to the components of the tumor. Treatment and prognosis will be dictated by the most malignant component. Please refer to:
- testicular seminoma
- testicular embryonal cell carcinoma
- testicular choriocarcinoma
- testicular yolk sac tumor
- testicular teratoma
