 Colorectal serrated lesions were divided into three groups : serrated adenoma(SA), typical hyperplastic polyp (THP) and atypical hyperplastic polyp (AHP). Serrated adenomas and THPs had a preponderance of occurrence in the distal colon, whereas AHPs were more often found in the proximal colon. The majority of SAs presented as protruded lesions, but THPs and AHPs were mainly flat-elevated. Serrated adenomas were usually reddish in color, but THPs and AHPs were more often normochromatic or slightly pale. The average size of the lesions was substantially bigger among SAs and AHPs than in THPs. In magnifying colonoscopic view, around 90% of the lesions with pinecone-like or fern-like pit pattern were SAs, but those with star-like pattern included not only THPs but also AHPs and SAs.

 There were 13 serrated lesions containing a cancerous part, whereas we encountered 991 early colorectal cancers as a whole during the same study period. Cancers were found in 6.3% of SAs no smaller than 5mm ; which was equivalent to 1.1% of all early cancers. Likewise cancers were found in 7.4% of AHPs no smaller than 5mm ; which was equivalent to 0.2% of all early cancers. Cancers occurring in AHPs were not associated with typical serrated adenomatous tissue. We speculate that carcinogenic pathways differ according to whether they are SAs or AHPs.

 There is confusion concerning the pathological diagnostic criteria and classification of serrated lesions. Accumulation of more cases and more discussion are necessary for the standardization of the concepts.
