title: [A case of adenocarcinoma arising in an ileal conduit].
abstract: We report a rare case of adenocarcinoma developing in an ileal conduit. A 78-year-old woman was referred complaining of abdominal pain. She had undergone radical cystectomy and ileal conduit formation for invasive bladder cancer 8 years previously. The pathological diagnosis was urothelial carcinoma, and distant metastasis was not found. She was lost to follow-up over 2 years postoperatively. Computed tomography at this time showed bilateral hydronephrosis. Metastasis was not revealed. Because renal failure progressed and gross hematuria developed, endoscopic examination through the stoma was performed. A mass adjacent to the ureteroileal anastomosis site was found. Biopsy led to a diagnosis of moderately differentiated adenocarcinoma. She died of renal failure 1.5 months after admission. To our knowledge, 9 cases of adenocarcinoma arising in an ileal conduit have previously been reported.
