 There is good correspondence between histological findings and pit pattern using magnifying colonoscopy. Type V pit pattern is divided into VI(irregular)and VN(non-structure). The former represents severely dysplastic adenomas and slightly invasive submucosal cancers, whereas the latter represents deeply invasive submucosal cancers. Magnifying colonoscopy has been established as a useful clinical diagnostic modality for determining depth of invasion in colorectal lesions. However, protruded type lesions with type VI pit pattern are not uncommonly proved to be deeply invasive of the submucosal layer. We recognized the limits of diagnostic methods for pit pattern at the moment.
