It usually affects females in their first two decades of life. It contains variable amounts of immature embryonal tissues. Based on the amount of immature neuroepithelial component, immature teratomas are graded from 1 to 3. The stage and grade of the tumor and the grade of the metastatic tumor are the important factors that predict prognosis. The use of cisplatin-based combination chemotherapy has significantly improved the survival rates of the patients.
