Microscopic colitis: a misnomer for a clearly defined entity?

In recent years, several endoscopic features of microscopic colitis have been noted. The pickup of these on colonoscopy depends on local expertise, endoscopic technology, and case volume. As the incidence of microscopic colitis has increased, we wanted to draw attention to endoscopists' ability to recognize such findings. We present eight cases of biopsy-proven microscopic colitis which demonstrate the spectrum of endoscopic findings. Endoscopists should actively search for such findings and target their biopsies, as new high-definition colonoscopes with sharper images, zoom capabilities, and high resolution allow a new vision into this syndrome.
