title: A rare case series of concomitant inflammatory bowel disease, sporadic adenomas, and serrated polyposis syndrome.
abstract: OBJECTIVE
  Inflammatory bowel disease (IBD) involving the colon is associated with an increased risk of colon cancer. Patients may develop sporadic adenomas further increasing their risk of colorectal cancer. Current knowledge of IBD with concomitant serrated polyposis syndrome (SPS) is limited. We describe four patients with both IBD and SPS.
  
  
  METHODS
  Four patients with inflammatory bowel disease and hyperplastic polyps referred to Beth Israel Deaconess Medical Center meeting the World Health Organization (WHO) criteria for SPS were identified.
  
  
  RESULTS
  Four patients with long standing IBD involving the colon were identified. All of these patients' IBD were in clinical remission. Additionally, 2 of the 4 patients were also noted to have sporadic adenomas. Each patient was also found to have multiple sessile serrated adenomas and hyperplastic polyps meeting the WHO criteria for SPS. Two of the patients had colonoscopy with chromoendoscopy which improved polyp detection. Discussions were held with each patient regarding the potentially increased risk of colorectal cancer with the combination of IBD and SPS. Patients were advised that colectomy would be the safest method to reduce the risk of cancer. None of the patients opted for colectomy and instead planned on a repeat colonoscopy with chromoendoscopy at 3-12 month intervals.
  
  
  CONCLUSIONS
  Serrated polyposis syndrome develops in patients with IBD. It is unclear how high the risk of colon cancer is in patients who have both IBD and SPS and what the recommendations should be regarding the frequency of surveillance or surgery. Further studies are necessary to identify the optimal management of these patients.
