 It is difficult to detect the depressed type of colorectal cancer early because of the lack of elevation of the lesions. However, early cancers which are depressed are clinically very important because they extend rapidly to underlying layers even though the lesion itself may be small. We analyzed the characteristic findings of depressed colorectal cancer known as the pit pattern with magnification endoscopy, comparing it with stereomicoroscopic examination. The magnification endoscopy enabled us to detect pit patterned lesions compatible with the stereomicroswpic diagnosis. These resuits suggest that the magnification endoscopy will improve the accuracy of endoscopic diagnosis.
