A 59-year-old man consulted a physician at this hospital with the chief complaint of lower abdominal pain and abdominal distension. He was hospitalized because of the diagnosis of large-intestinal obstruction due to sigmoid colon cancer. CEA was elevated at 74.4 ng/ml. His condition improved with conservative medical management though he developed septicemia, septic shock, acute renal failure, and a cardiac failure after decompression with a transanal ileus tube. CEA decreased to 1.9 ng/ml at the examination after his general status and ischemic colitis had improved, and we judged the transitory CEA rise to be caused by the ischemic colitis. We performed laparoscopy-assisted surgery on the sigmoid colon cancer, and found longitudinal superficial ulcers on the oral side of the tumor. The pathologic diagnosis was ischemic colitis. We added some bibliographical considerations and reported this rare case of ischemic colitis that showed an abnormally high CEA level in the sigmoid colon cancer.
