title: [Metastatic small intestinal tumor associated with transitional cell carcinoma: a report of 2 cases and review of cases in Japan].
abstract: Transitional cell carcinoma (TCC) frequently metastasizes to lymph nodes, liver, lungs and bone. However, metastasis to the gastrointestinal tract is rare. We report two cases of bladder tumor which metastasized to the ileum. According to the literature, these are the 7th and 8th cases in Japan. Case 1: A 87-year-old man had a history of bladder tumor (TCC, grade 3, pT2bN0M0) and has transurethral resection of bladder tumor (TUR-BT) three times. Two months after the last TUR-BT, he was admitted with ileus. As computed tomography (CT) showed abdominal free air, our diagnosis was perforation of gastrointestinal tract. The patient received an operation which resected partial ileum. We found the elastic hard tumor in the ileum on the perforated lesion, which showed metastatic TCC in the ileum pathologicaly. Case 2 : A 53-year-old man visited our hospital with gross hematuria. Cystoscopy showed a non-papillary broad based tumor in the right wall of the bladder. CT showed a bladder tumor invaded into the prostate (pT4aN1M0), we performed total cyctectomy and ileal conduit after neo-adjuvant chemotherapy. During the operation, we found the tumor (2 cm in diameter) in the small intestine which was metastasized of bladder tumor.
