An Unusual Testicular Metastasis from Transitional Cell Carcinoma of the Ureter: A Case Report

罕見的輸尿管移形上皮細胞癌引起的睪丸轉移-一病例報告

摘要


輸尿管移形上皮細胞癌轉移到睪丸相當罕見,本文報告依病例為左側輸尿管腫瘤接受廊清性腎輸尿管切除及膀胱袖口切除術後再輔以放射治療和化學治療,術後五個月後患者左側睪丸有一腫塊,我們實行左側廊清性睪丸切除術,病理切片證實為輸尿管移形上皮細胞癌轉移到睪丸,經由文獻回顧發現這是第二例由輸尿管腫瘤轉移引起的睪丸腫瘤。輸尿管腫瘤患者在睪丸有摸到腫塊時雖然沒有發現身體其他部位轉移,仍然必須考慮轉移性睪丸腫瘤。

Testicular tumor metastasis from transitional cell carcinoma (TCC) of the ureter is very rare. Herein, we report a case who presented with a palpable mass of left testis, after he underwent radical nephroureterectomy and bladder cuff excision and adjuvant radiotherapy and chemotherapy for the TCC of left ureter tumor for 5 months. We performed left radical orchiectomy and histology revealed a TCC identical to the original ureteral tumor. In a review of the literature, we found this case was the second case of metastatic testicular tumor from the ureteral TCC. In patients presenting the symptom of a palpable testicular mass, if they are known to have a ureteral TCC, metastatic neoplasm should be considered in the differential diagnosis, even if in the absence of other systemic metastasis.
