 Recently so called“serrated lesions”have been reported to be the precursor lesion of colorectal carcinoma with MSI high. On the other hand there are some clinical and pathological problems in them. We have studied their endoscopic characters through the translational research that we cooperated with histological and genetic analysis based on endoscopic observation using high resolution magnifying colonoscopy. In the result, we have understood to be able diagnose as SSA/P(sessile serrated adenoma/polyp)on same pathological and genetic lesion, which indicated both flat shaped and type II-open shaped(type II-O)pit pattern. And serrated lesions changed histological and form by another pit patterns other than type II-O being added. We summarized those SSA/Ps, which had malignant potential indicated upheaval tendencies and another pit patterns other than type II-O pit pattern. Moreover, we found out some subjects about TSA and intermediate lesions, and concluded that accumulation and translational research of the further cases were required.
