title: Partial obstruction of the sigmoid colon by surgical implantation.
abstract: Invasive transitional cell carcinoma of the bladder is known to extend directly to other organs in the pelvis. When metastases occur they almost always adhere to a rather consistent pattern of dissemination. We present an unusual case of partial obstruction of the sigmoid colon due to a metastatic transitiocellular bladder tumour four months after transurethral resection of the tumour complicated with a perforation into the peritoneal cavity. Direct implantation of the tumour with the resectoscope is the most possible explanation, but seeding on an intact serosa cannot be excluded either.
