title: Relapsed colon cancer patient presenting with hematuria 13 years after primary tumor resection: a case report.
abstract: We report a rare case of postoperative colon cancer recurrence who presented with hematuria 13 years after resection of the primary colonic cancer. The patient was 72 years of age and underwent surgical resection of sigmoid colon cancer at another regional hospital in 1994. Since June 2007, this patient has complained of hematuria and bloody stool. On physical examination, tenderness and a hard, indurated mass was palpable in the lower mid-abdomen. Abdominal computed tomography showed a metastatic tumor at the lower midline peritoneum with invasion of the adjacent abdominal wall. Her serum carcinoembryonic antigen level was elevated to 32 ng/dL. Histopathology revealed metastatic colonic adenocarcinoma in the jejunum and abdominal wall.
