Adult testicular pure yolk sac tumor

Here we describe the clinical, ultrasonographic and histological features o f a rare pure adult yolk sac tumor detected in the right testis of a 44-yea r-old male. Due to the rarity of this neoplasm (less than 10 cases have bee n reported), there is no unanimous consensus for therapy following inguinal orchiectomy. We believe that nerve-sparing retroperitoneal lymph node diss ection could be potentially curative and useful for future interpretations of this tumor's potential evolution. Copyright (C) 2001 S.
