Verrucous Carcinoma of the Renal Pelvis and Ureter: A Case Report in Taiwan

腎盂與輸尿管疣狀癌:台灣一病例報告

摘要


疣狀癌是一種良好分化的鱗狀細胞癌,也是一種很少出現遠端轉移的低度惡性腫瘤。根據過去報告的病例中,它的發生可能是因結石的出現造成慢性發炎和外傷性的刺激,這樣的機制將促進上半部泌尿道疣狀癌的發展。我們在此報告一例發生在右側腎盂與輸尿管的疣狀癌,這樣的腫瘤造成嚴重的泌尿道阻塞。手術治療是主要治療模式。這位病患接受腎盂及輸尿管切除手術。此外因為在顯微鏡裡看到殘留腫瘤在輸尿管切口端部,該病患也接受了術後輔助性放射治療。

Verrucous carcinoma (VC) is a well differentiated squamous cell carcinoma that is a low-grade malignancy and rarely presents with distant metastasis. According to previously reported cases, it is possible that the presence of calculi may cause chronic inflammation and traumatic irritation; this mechanism seems to promote the development of VC in the upper part of urinary tract. We present a case of verrucous carcinoma of the right renal pelvis and right ureter. Such tumors may cause severe urinary tract obstruction. Surgical treatment is the main modality of therapy. This patient received nephro-ureterectomy. Furthermore, because a microscopic residual tumor was found at the cut end of ureter, the patient also received adjuvant radiotherapy.
