Transitional cell carcinoma in orthotopic ileal neobladder 12 years after radical cystectomy

Some cases of secondary adenocarcinoma developing in the replaced bowel segment of urinary diversions have been reported so far. Secondary adenocarcinoma develops 20 years after surgery in about 0.5% of those in whom an ileal segment is used. There have been several reports in the literature describing extensions of transitional cell carcinoma (TCC) from the distal urether into an ileal conduit. Histology of loop tumor in 50% was TCC. The site of tumors in the majority of cases is the area at the uretheral orifices or the stoma.
