European consensus on the histopathology of inflammatory bowel disease.
The histologic examination of endoscopic biopsies or resection specimens remains a key step in the work-up of affected inflammatory bowel disease (IBD) patients and can be used for diagnosis andExpand

Flat neoplastic lesions of the colon and rectum detected by high-resolution video endoscopy and chromoscopy.
Because small flat colorectal neoplastic lesions (i.e., flat adenomas and flat adenocarcinomas) may be as translucent as the surrounding mucosa, they can remain undetected at conventional endoscopy.Expand
