The patient is a women in her 60s. After medical examinations, she was told that the result of fecal occult blood reaction testing was positive. Moreover, colonoscopy found type 2 cancer in her sigmoid colon. The patient underwent sigmoidectomy. The 3D dissection of lymph node and colorectal side-to-end anastomosis were performed. Pathologically, the case was diagnosed as moderately differentiated adenocarcinoma (stage II). Adjuvant chemotherapy was not given. During follow-up observation, the tumor marker levels were elevated above normal. A work-up revealed a recurrence of the cancer on the abdominal wall. The lesion was surgically removed with a margin of about 2 cm from the tumor secured. Pathological diagnosis of this recurrent case was not inconsistent with the previous diagnosis of sigmoid colon cancer. As the relapse was thought to be due to the implantation of cancer cells in the abdominal wall, we need to follow the surgical procedure with scrupulous care and exercise the utmost precaution to protect incision wound on the abdominal wall.
