Abstract
A 67-year-old man presented with the complaints of fever, right-sided coxalgia, and right lower abdominal pain. An abdominal CT revealed a thickened wall of the appendix and abscess formation in the right iliopsoas muscle. Subsequent colonoscopy confirmed diagnosis of cecal cancer (moderately differentiated adenocarcinoma) with an iliopsoas muscle abscess. A laparoscopy-assisted ileocecal resection with D3 lymph node dissection and abscess drainage were performed. A few detectable disseminations were detected in the small intestinal mesentery, but all the visualized lesions were fully resected. There have been reports of colon cancer complicated by iliopsoas muscle abscess, but this is the only case in which the condition was treated by laparoscopic surgery. Laparoscopic-assisted surgery allows us to identify local lesions and observe the retroperitoneum at a low level of invasiveness. This case would be of interest for adaptation and the expansion of laparoscopic surgery.
