Phlebosclerotic Colitis Mimicking Colon Cancer

A 59-year-old Korean man presented to the gastroenterology clinic at Kosin University Gospel Hospital for the management of abnormal findings on colonoscopic examination. The patient was healthy when he visited our clinic. Two months before presenting to our hospital, the patient previously underwent colonoscopic examination for a health checkup at another hospital. The examination revealed asymmetric edematous dark-bluish colonic mucosa and sclerotic changes of the colonic walls with engorged vessels from the cecum to the proximal ascending colon. The patient was referred to our clinic on May 25, 2016.
