Also called Non-dysgerminomatous germ cell tumor of testis · Testicular non seminomatous germ cell tumor · Testicular non-dysgerminomatous germ cell tumor
What it is
A form of testicular germ cell tumor occurring in the third decade of life with a usually painless unilateral mass in the scrotum or, in some cases, with gynaecomastia and/or back and flack pain. The clinical course is more aggressive than testicular seminomatous germ cell tumors with rapid involvement of blood vessels and a poorer prognosis. Histologically, the tumour can be either undifferentiated (embryonal carcinoma), differentiated (teratoma, yolk sac tumor, choriocarcinoma), or can consist of a mixture of seminomatous and nonseminomatous components.
