Endoluminal metastasis of colon cancer to the urinary bladder via the ureter: report of a case.
A 67-year-old woman was admitted for intermittent gross hematuria. Her medical history included a right colectomy for cancer of the ascending colon and removal of metastatic nodes adjacent to the right internal iliac vessels, respectively at 63 and 65 years of age. Cystoscopy detected a semi-pedunculated, nonpapillary (3.5-4 cm diameter) tumor situated above the right ureteral orifice. The histological evaluation of the resected specimen revealed metastatic colonic adenocarcinoma. The history and pathological findings were consistent with a mechanism of endoluminal implantation of adenocarcinoma of the large bowel to the bladder via the right ureter.
