A pure triphasic testicular wilms tumor of primordial germ cell origin.

摘要

Vanasupa et al. reported recently in the Journal on a young patient with a testicular tumor that was a mixed nonseminoma composed of embryonal carcinoma, yolk sac tumor, a Wilms tumor component (nephroblastoma), and rhabdomyosarcoma. They conclude that this has never been reported before and that the development of a Wilms tumor in a testis is rare and can be explained by activation of the WT1 gene.
