Sumario:Serrated polyposis syndrome (SPS) was formerly considered a rare condition. In the past decade, it has gained increasing recognition due to its close association with colorectal cancer (CRC). Diagnosis is made based on the updated World Health Organization (WHO) criteria of having serrated polyps (SPs) proximal to the rectum, all being ≥5 mm in size, with at least two being ≥10 mm in size (criterion I), and a more distal phenotype that presents with greater than 20 SPs of any size throughout the large bowel with five being proximal to the rectum (criterion II). There are three subtypes of SP: hyperplastic polyp (HP), sessile serrated lesion (SSL), and traditional serrated adenoma (TSA). We present a 61-year-old Caucasian male who was referred for surveillance colonoscopy due to a history of colon polyps. A total of 28 polyps were completely removed, 21 of which were found to be SPs, three of which were >10 mm in size, meeting the WHO criteria for SPS. A follow-up colonoscopy was recommended in one year. It is now recognized that SPS are significant contributors to the development of CRC. The United States Multi-Society Preventive Task Force recently updated their consensus statement in 2020 with specific guidance for surveillance of SPs. It is important to emphasize that the diagnostic criteria apply to cumulative polyp count over the individual’s lifetime. The optimal surveillance for SPS remains unclear.
