Juvenile colonic polyposis

What it means

The presence of more than 5 juvenile polyps of the colon. The term juvenile polyps refer to a special histopathology and not the age of onset as the polyp might be diagnosed at all ages. The juvenile polyp has a spherical appearance and is microscopically characterized by overgrowth of an oedematous lamina propria with inflammatory cells and cystic glands.

A juvenile polyp is a hamartomatous growth that projects from the lining of the intestine. It does not arise from the colonocytes themselves but from the tissues underneath the lining cells.
