Concomitment spread of a renal cell carcinoma beyond the kidney and a transitional cell carcinoma beyond the bladder

We report the case of a 61-year-old man, with a rare combination of two advanced urological tumors: a concomitant spread of an adenocarcinoma beyond the kidney and a urothelial carcinoma beyond the bladder. We simultaneously performed a primary curative prostatovesiculectomy and a nephroureterectomy on the right with ileal neobladder. To our knowledge, a case report of concomitant spread of an adenocarcinoma beyond the kidney (pT3 pN0 M0 G3) and a urothelial carcinoma beyond the bladder (pT3a pN0 M0 G3) with subsequent curative therapy has thus far not been published. A combination of the two diseases described here is obviously a remarkable rarity.
