[Synchronous presentation of inverted papilloma with transitional carcinoma focus in right kidney pelvis and bladder urothelial carcinoma].
We report a case with synchronous presentation of inverted papilloma (I.P) and transitional cell carcinoma of the right renal pelvis (pT2G1) associated to urothelial carcinoma on left lateral wall of the bladder (T1G2). Urothelial inverted papilloma is an uncommon, generally benign tumor that account for 2.2% of all urothelial tumors. Although the preferred location is the bladder (90%), above all in trigone and bladder neck, also can be located at the UUT "upper urinary tract" (7-8%) and urethra (3%). A close follow-up is recommended after conservative therapy, mainly endoscopic procedure, due to likelihood of recurrence and synchronous or metachronous association with transitional cell carcinoma.
