Juvenile polyposis syndrome (JPS) is a non-cancerous benign growth predominant in a young population with an estimated incidence of one in 1, 00,000 to 1, 60,000 per year. It is a rare genetic presentation, which can occur sporadically as well. There is a 39% evident risk of developing colorectal carcinoma. Herein, we present an unusual case of a 13-year-old girl from a rural area with a negative family history of juvenile polyposis, who had complaints of rectal prolapse and rectal bleeding which were more pronounced after defecation. Her contrast computed tomography (CT) scan revealed a distended large bowel studded with multiple juvenile polyps throughout, the largest of which was detected on the mid rectum. Colo-colic intussusception was also found due to a large polyp at the hepatic flexure, inferiorly extending up to ascending colon and caecum. Pan proctocolectomy with ileoanal J pouch anastomosis was performed, bearing in mind the risk for colorectal cancer and her general state of health.
