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.

A Mucinous Colon Adeno Carcinoma Relapse 20 years after Primary Tumour Treatment? A Case Report and Case Report on the Role of FDG-PET/CT in Mucinous Cancers

“…Our patient presented with a diagnosis of metastatic colorectal mucinous adenocarcinoma 20 years after completing curative treatment for a former mucinous colon cancer with signet-cell variant, which is a very aggressive histological type featuring early-relapses and dismal prognosis. Based on a MEDLINE literature search spanning the period between January 1966 and December 2016 no relapses of a colorectal cancer beyond 13 years [8] have ever been documented. This raised the question on if our findings were actually a true relapse, appealing to the mucinous histology shared by both tumours versus a metachronous second malignancy of the colon.…”
