Bilateral testicular lymphoma treated with chemotherapy and radiation without orchiectomy: complete response relapsed at 52 months in the vitreous humor.

We report the first detailed case of testicular lymphoma managed with chemotherapy and radiation without orchiectomy. A 60-year-old man with Stage II extralymphatic bilateral testicular lymphoma refused orchiectomy, but underwent cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy and radiation. He remained disease free for 52 months, when a solitary central nervous system relapse to the vitreous humor was diagnosed. The optimal therapy for testicular lymphoma is unclear but often includes orchiectomy with adjuvant chemotherapy and radiation. Stage I testicular lymphoma can be cured by surgery alone; however, the relapse rates for all stages of testicular lymphoma are high despite systemic therapy. For Stage II disease and higher, chemotherapy/radiation is recommended; orchiectomy may not be mandatory.
