متن کاملSerrated polyposis syndrome associated with long-standing inflammatory bowel disease.
Inflammatory bowel disease (IBD) patients are at an increased risk of developing colorectal cancer (CRC), which is thought to develop via the adenoma-carcinoma pathway. Since the discovery of the serrated carcinogenesis pathway and serrated polyposis syndrome (SPS), the incidence of carcinomas arising from serrated lesions in IBD patients has increased. We report three cases of long-standing IB...
متن کاملSerrated Polyposis Syndrome in a Single-Center 10-Year Experience
