The primary testicular cancers are classified as testicular germ-cell tumors and non-germcell tumors of the testis. The testicular germ-cell tumors constitute approx 90 to 95% of all testicular cancers, whereas the incidence of non-germ-cell tumors of testes is usually less than 10% (1). The testicular germ-cell tumors include seminoma, embryonal carcinoma, and teratoma with or without malignant transformation, choriocarcinoma, and yolk sac tumor (also known as endodermal sinus tumor, or embryonal adenocarcinoma of the prepubertal testis) (1).
