[A Case of Surgery for Abdominal Wall Metastasis of Colorectal Cancer to Improve the Quality of Life].

The patient was a 47-year-old woman who underwent partial colon resection and medial segmentectomy of the liver via laparotomy for descending colon cancer with a metastatic liver tumor. Postoperative chemotherapy was administered. Six months later, she developed pelvic recurrence and subsequently underwent bilateral adnexectomy, hysterectomy, and lymph node dissection, which confirmed colorectal metastasis. Two years and 6 months after the initial surgery, a gradually enlarging abdominal wall mass was detected. As the mass rapidly increased in size and became painful, an abdominal wall metastasis from colorectal cancer was suspected. Surgical intervention was deemed necessary to prevent deterioration in the patient's quality of life due to potential tumor ulceration. The tumor was resected under general anesthesia, including partial resection of the rectus abdominis muscle. Histopathological examination confirmed metastasis from colorectal cancer. Postoperatively, the patient's abdominal wall pain resolved. At the time of reporting, the patient had died of pulmonary metastasis, although there was no local recurrence at 1 year and 2 months postoperatively.
