We report herein a case of solitary small intestinal recurrence of colorectal cancer. A man in his 70s underwent ileocecal resection with regional lymph node dissection for cecal cancer at Okayama University Hospital in December 2004. The tumor was diagnosed as moderately differentiated adenocarcinoma, and graded as pStage Ⅱ (pT2pN0cM0) according to the Japanese Classification of Colorectal Carcinoma, eighth edition. Thirty-six months after initial surgery, he presented complaining of severe abdominal pain and high fever. Abdominal computed tomography showed localized intra-abdominal abscess. Based on the diagnosis of intestinal penetration, we performed an emergent operation. Intraoperatively, a small intestinal tumor was found to be the cause of the penetration; therefore, both partial resection of the ileum and abscess drainage were performed. Although the patient underwent adjuvant chemotherapy, the tumor recurred in the retroperitoneum in November 2008. He then underwent multimodal therapy, including palliative local resection, radiotherapy, and systemic chemotherapy, to the site of recurrence; however, he died of the cancer about six years after initial recurrence.
