Abstract
- Solitary juvenile polyps are the most common benign hamartomatous polyps in childhood presenting with painless rectal bleeding. It is rare in solitary juvenile polyps with adenomatous change which is associated with increased risk for gastrointestinal cancer. We report a rare case of a solitary juvenile polyp with adenomatous change and causing colonic intussussection in a 6 year old girl, who presented symptoms of lower abdominal pain, vomiting, and hematochezia. The colonic intussussception was reduced during the colon barium study and a polypoid round mass shadow at the splenic flexure was formed. On colonoscopy, it was seen as a single huge polyp impacted to the splenic flexure lumen. Endoscopic polypectomy was performed. The histologic evaluation revealed the characteristic features of a juvenile poloyps with adenomatous change.
