Figure 1. A case of colorectal sessile serrated lesion. The lesion shown in Figure 1 is a sessile serrated lesion (SSL) detected during a colonoscopy. SSLs are often flat and macroscopically normal to pale in color, as shown in this case, and can be easily overlooked. The detection of SSLs is important, and the detection rate of SSLs may be a quality measurement of colonoscopy.
