However, synchronous bilateral testicular tumors with different histology were a quite rare situation. We reported the first case of successful radical orchiectomy in the left scrotum and testicular sparing surgery in the right testis sequentially. No atrophy or residual tumor in the right testis and no recurrence in the left scrotum were found after 7 years of follow-up. Ethical approval was obtained from the Institutional Review Board of Childrens Hospital of Shanghai, which was affiliated to the Shanghai Jiao Tong University, School of Medicine, Shanghai, China. Informed consent was obtained from his parents.展开更多
