| Abstract: | It has recently come to be thought that cases of juvenile polyposis have a natural tendency to develop adenoma and/or carcinoma. Here we present a case of juvenile polyposis coli with adenomatous change in a 21-year-old male, with a review of 34 cases of juvenile polyposis in the Japanese literature, and discuss the pathogenetic development of the polyps and their malignant potential. In this case, focal or entire adenomatous areas were found in large part of the polyps in the resected sigmoid colon and rectum, though these findings had not been recognized in 23 polypectomy specimens from the rectum 10 months prior to the operation. It was suggested that adenomatous change developed quickly in a very short time. |
