腎癌・肝癌・遺残尿管癌の異時性重複癌の1例

Abstract

A case of asynchronous triple cancer in an 88-year-old male is reported. Six years ago, he had received left radical nephrectomy for renal cell carcinoma, and 2 years ago partial hepatectomy for hepatocellular carcinoma detected by follow-up computed tomography (CT). During the post-operative follow-up, no metastasis of either the renal or hepatic carcinoma was detected. On February 12, 1997 he presented with macroscopic hematuria. Cystoscopy revealed a tumor emerging from the left ureteral orifice, while CT and magnetic resonance imaging (MRI) revealed a tumor mass in the left exterior of bladder. Diagnosis of residual ureter tumor, we performed both left ureterectomy and partial cystectomy. Histological diagnosis revealed transitional cell carcinoma of the residual ureter (G2 > G3, pT1, pV0, pL0, pR0). Convalescence was uneventful and 10 months after the operation, he is alive with no recurrence or metastasis. We stress the importance of careful follow-up not only to perceive the recurrence or metastasis of renal cancer but also to detect cancer in other parts of the body.
