Recurrence in the abdominal wall is rare after resection for rectal cancer. Here we report two such recurrence cases. Case 1: A 72-year-old man underwent Hartmann's procedure for rectal cancer. The histological findings of the tumor showed moderately differentiated adenocarcinoma (se, n1, ly3, v1, P0, H0, M (-), stage IIIa). Nineteen months after resection, recurrence in the operative wound scar and lung metastasis (solitary) were found. Recurrence in the abdominal wall and lnug metastasis were resected. Case 2: A 53-year-old man unederwent resection of the rectum for rectal cancer. The histopathological findings of the tumor showed moderately differentiated adenocarcinoma (a1, n1, ly2, v0, P0, H0, M (-), stage IIIa). Fifty-two months after resection, recurrence in the operative wound scar was found, and resections of the abdominal wall and part of the bladder wall were carried out. We thought the recurrences were caused by implantations of the cancer cells when the operative woudns were closed. These two cases are the first evidence of recurrent rectal cancer in operative wound scars.
