[Primary intestinal type adenocarcinoma of the urinary bladder: a case report].
A 43-year-old man was referred to our hospital with complaints of macroscopic hematuria, micturition pain, and pollakisuria. Cystoscopy revealed a papillary broad-based tumor of 4 cm in diameter at the posterior wall and trigone of the urinary bladder. A punch biopsy specimen was diagnosed histopathologically as adenocarcinoma mimicking colorectal cancer. Computed tomographic (CT) scan demonstrated a large tumor involving both the urinary bladder and the rectum. Total cystoprostatectomy and low anterior resection following colorectal anastomosis, double barreled colostomy, and ileal conduit urinary diversion were performed. The tumor was diagnosed histopathologically as primary intestinal type adenocarcinoma of the urinary bladder infiltrating the sigmoid colon and the small intestine. The patient died 12 months after the operation due to peritonitis carcinomatosa.
