title: [Case report: collecting (Bellini) duct carcinoma during the follow-up for bladder cancer].
abstract: A 78-year-old man had undergone transurethral resection of bladder tumor (TUR-Bt) 6 times since he was diagnosed as having bladder cancer. Past histology was urothelial carcinoma, pTa, G1-G2. During the follow-up, recurrent bladder cancer was found. Enhanced computed tomography and drip infusion pyelography revealed pelvic cancer with tumor embolus in the inferior vena cava. Therefore, TUR-Bt and total ureteronephrectomy with removal of the thrombus from the vena cava was performed. The histopathological diagnosis was urothelial carcinoma of the bladder and Bellini duct carcinoma of the kidney, but in immunohistostaining surgical specimen of both bladder and kidney showed some similarities. This disease is rare. Several reports indicate an association between Bellini and urothelial carcinoma. We describe the case of the Bellini duct carcinoma of the kidney during the follow-up for bladder cancer with possibility of the association between Bellini and urothelial carcinoma.
