This is the case of a 70-year-old woman who has a history of multiple colonic polypectomies. The history of the resection specimen had revealed hyperplastic polyps and serrated adenomas. Altogether, this patient fulfills the diagnostic criteria of having a hyperplastic polyposis syndrome. This syndrome is associated with a significantly increased risk of colonic carcinomas, and, therefore, complete detection and resection of lesions at surveillance colonoscopy is mandatory.
Here, colonoscopy with indigocarmine chromoendoscopy is performed to detect serrated lesions in the right hemicolon. A complicated lesion at the appendiceal orifice is resected.
