title: [Juvenile colonic mucosal polyps in adults].
abstract: The histology of all intestinal polyps removed endoscopically during the last 30 months has been reviewed. Among the 90 patients with a total of 154 polyps, 3 cases of juvenile polyps were found. All three were male adults who were aged 29, 34, and 50 years. In two patients the lesion was solitary, while one had polyposis with about 100 polyps. Macroscopically the juvenile polyps cannot be distinguished from adenomatous polyps, but their histologic appearance is typical. They are considered to be hamartomas and have no tendency to become malignant. Thus, juvenile polyposis does not represent a precancerous lesion as adenomatous polyposis does, and must therefore be treated differently. Therapy consists of endoscopic removal of all polyps. In order to differentiate juvenile from adenomatous polyps with certainty, histological examination of at least one polyp is necessary. This differential diagnosis is the indispensable precondition for appropriate therapy.
