Three Cases of Bilateral Metachronous Testicular Tumors
We present three cases of bilateral metachronous testicular tumors. The patient in case 1 had a history of left orchiectomy for undescended testis at the age of 19. The pathological findings revealed germ cell neoplasia in situ. Twenty-four years later (age＝43), he was diagnosed with right testicula...

| Zusammenfassung: | We present three cases of bilateral metachronous testicular tumors. The patient in case 1 had a history of left orchiectomy for undescended testis at the age of 19. The pathological findings revealed germ cell neoplasia in situ. Twenty-four years later (age＝43), he was diagnosed with right testicular tumor with lymph node and lung metastasis (stage IIIc). Right orchiectomy was performed, and the pathological finding showed nonseminomatous germ cell tumor. He underwent chemotherapy, followed by lymph node dissection and lung metastasectomy. The patient in case 2 had a history of left orchiectomy for testicular tumor at the age of 41. The pathological finding of the left testis revealed seminoma (stage IA). Nineteen years later (age＝60), he was diagnosed with right testicular tumor and underwent right orchiectomy. Herein, the pathological finding showed seminoma (stage IA). The patient in case 3 had a history of right orchiectomy for testicular tumor at the age of 25. The pathological findings revealed seminoma (stage IS), and he underwent adjuvant radiation of the para-aortic field without subsequent recurrence. Fourteen years later (age＝39), he was diagnosed with left testicular tumor and underwent left orchiectomy. The pathological finding revealed seminoma (stage IB). The patient underwent adjuvant carboplatin monotherapy to prevent recurrence. Due to the long interval between the occurrence of bilateral metachronous testicular tumors (mean＝19 years ; three cases), long-term observation is necessary to detect the possible occurrence of contralateral testicular tumors. Contralateral testicular biopsy might be considered at the time of orchiectomy for unilateral testicular tumor if associated with testicular atrophy and/or a history of undescended testis |
