Rectal neuroendocrine tumors in a colon cancer screening colonoscopy program. Sixteen-year single institution experience.

Rectal NETs are detected in the screening colonoscopy program. In majority of cases, they are not suspected by endoscopists on colonoscopy, but diagnosed after removal in histopathological examinations. There is a need of education of endoscopists in recognition and methods of treatment of rNETs.
