Bilateral synchronous testicular cancer: A case report

Introduction and importance: Testicular cancer is the most common type of malignancy in young adult males, accounting for 1 % of all cancer diagnosis in men and 5 % of all urologic tumors. It is one of the malignancies with the highest cure rate. Bilateral germ cell tumor of the testicles is rare, representing only 1 % of all new cases of testicular cancer, around 30 % of which occur synchronously. Interestingly, there is not yet an occurrence where the bilateral synchronous testicular cancer has different histopathological type. Case presentation: In this paper, we performed bilateral radical orchiectomy in different occasion, followed by adjuvant chemotherapy (BEP regiment). Clinical discussion: Since the clinical result is excellent, this finding could be a breakthrough in testicular cancer study. A cellular communication between different cancer cell type through chemokine which could affect response to chemotherapy. Conclusion: Treatment with surgery and chemotherapy is well tolerated and received. A further specific clinical study needs to be performed to investigate this finding in the future.
