433 endoscopic feature of depressed type colorectal neoplasms in magnifying endoscopy and endocytoscopy

Colorectal cancers are generally recognized to develop from polyps. This “adenoma-adenocarcinoma sequence” theory has been in the mainstream of development of colorectal neoplasms. However, another theory was revealed, which is considered to emerge directly from normal epithelium, not through the adenomatous stage. This theory is called “de novo” pathway. Now, it is possible to presume the histology of colorectal lesions using magnifying endoscopy (×100 folds, pit pattern classification) and endocytoscopy (×520 folds, EC classification).
