The development of metastasis to the duodenum and of bladder cancer to the intestine is very rare. We report such a case.<BR> A 75–year–old man undergoing total cystectomy 4 years earlier for bladder cancer was admitted for chemotherapy for paraaortic lymph node recurrence.<BR> Upper gastrointestinal endoscopy showed a duodenal bulb ulcer scar and descending duodenum stenosis. The pathological duodenal specimen diagnosis was unresectable adenocarcinoma, i.e., a clinical diagnosis of duodenal carcinoma. Gastrojejunostomy was done to unable oral parenteral nutrition. A hard mass in the descending duodenum and enlarged gastric lymph nodes suggested metastatic transitional cell carcinoma confirmed by immunopathological examination.<BR> The final diagnosis was transitional cell carcinoma of the bladder with duodenum and paraaortic lymph node metastasis.
