Juvenile Polyps (JP) are rare but important causes of acute gastrointestinal symptoms in children. They are a recognized cause of painless rectal bleeding in preschool age children and also the most common intraluminal disorder of the colon in children. They are often solitary, pedunculated and small in size but may occasionally grow to large sizes or occur in great numbers, as in juvenile polyposis syndrome. Histologically juvenile polyps are similar to inflammatory polyps with irregular dilated glands, lamina propria expansion and granulation tissue expansion. Sporadic juvenile polyps of the colon occur in up to 2 percent of children under the age of 10 years, are usually solitary, and are not associated with an increased cancer risk.
