We describe herein a 60-year-old female with an operative wound-scar recurrence 19 months after curative resection for sigmoid colon cancer. She has been well, to date, with no evidence of recurrence for more than six years since the second operation. At the first surgery, intraoperative and histopathological findings of the sigmoid colon cancer were as follows: macroscopically type 2, 6×4 cm in diameter, SE PO HO M (-) D3, se, ly0, v0, n (-). Nineteen months after the operation, a tumor (3×3 cm) appeared in the median incisional scar near the umbilicus. Subsequently, an other operation was performed. The abdominal wall, with 2 cm disease-free margins, and the part of the small intestine adhering to the tumor were resected. Marlex mesh was used to close the abdominal wall defect. No other recurrent lesion was found and the resected tumor was diagnosed as moderately differentiated adenocarcinoma, a metastasis from the colon cancer. It was suggested that the implantation during colon surgery caused the operative scar recurrence.
