 A sixty-one-years old male was pointed out as having a pedunculated lesion at the sigmoid-descending colon junction. White light observation showed the pedunculated lesion in the sigmoid colon with reddish and congestive appearance on the surface. NBI(narrow band imaging) observation and magnifying endoscopy under crystal violet dying of the depressed area showed no findings suggesting submucosal invasion. Diagnostic polypectomy was performed and consequently the lesion was pathologically diagnosed as early colon cancer with vascular involvement and submucosal invasion of 3,300μm. This case suggests that endoscopic diagnosis should be performed based not only on image enhanced endoscopy findings but also on conventional endoscopy findings.
