We report seven adolescents presenting with hematochezia. Five had a family history of colonic polyps or cancer. Colonoscopy showed either multiple pedunculated and/or sessile polyps with partial or total colonic involvement. Polyphistopathology was of the juvenile retention, hamartomatous or tubular adenomatous type. Total proctocolectomy was done in four patients, two underwent repeated polypectomy, and one is awaiting further treatment. An increased awareness of colonic polyposis is important due to the risk of malignant transformation.
