title: [A case of regional advanced colon cancer accompanied with right femoral nerve paresis].
abstract: The patient is a man in his sixties. A hard tumor that fixed to right iliac bone as big as an adult fist could be palpated in the ileocecal region. He complained a cramp and pain in the right thigh. Computed tomography of the abdomen after the administration of contrast material showed an irregular shape tumor that highly invaded through right iliac muscle, and it widely attached to the right iliac bone. Any distant metastases were not detected. In the abdominal cavity, any peritoneal dissemination nodules were not detected. The tumor was completely removed by excising with periosteum of the iliac bone, iliac muscle, transversus abdominis muscle, and a part of psoas muscle and femoral nerve. The dead space after radical excision was filled with greater omental flap. In the microscopic examination, the tumor was diagnosed moderately differentiated adenocarcinoma with invasion to serosa, muscles, femoral nerve and periosteum and regional lymph nodes involvement. The carcinoma cell was not seen in the excised margin, thus it was judged that it was curative excision. If the colonic cancer obtains the curative excision even if the permeation of the limited part is advanced, an excellent prognosis can often be expected, and the role that the surgical operation plays as limited part treatment is large.
