title: Juvenile polyps and juvenile polyp syndromes in children: a clinical and endoscopic survey.
abstract: In children, most colonic polyps are juvenile polyps with negligible risk for malignant transformation. The exception is juvenile polyposis syndrome (JPS) where there is a risk for developing colon cancer. The authors studied differences in clinical features and colonoscopic findings in children with solitary juvenile polyps (SJP), multiple juvenile polyps (MJP), and JPS.
  
  
  METHODS
  Children were identified as SJP (1 polyp), MJP (2-4 polyps), or JPS (>5 polyps). Demographic data, laboratory values, family history, and colonoscopic findings were recorded.
  
  
  RESULTS
  Children having polypectomy had juvenile polyps (93%), adenomatous polyps (5%), and Peutz-Jegher syndrome (3%). Juvenile polyps were classified as SJP (67%), MJP (16%), and JPS (17%). Children with SJP were younger, were more likely to have polyps limited to the rectosigmoid colon, and had larger polyps than children with MJP and JPS. Anemia was more common in JPS than MJP and SJP.
  
  
  CONCLUSIONS
  Clinical and endoscopic findings differ between SJP, MJP, and JPS.
