  ICD-10: Q85.8

This is a hamartomatous polyp of the small bowel, probably caused by Peutz-Jeghers syndrome.

- Only a small section of normal small bowel mucosa can be seen on this specimen.
- The main part of the specimen shows a hamartomatous polyp with bundles of smooth muscle extending in a tree-like fashion. The smooth muscle is covered with epithelium, partly villous and partly tubular, as well as lamina propria. The covering epithelium looks similar to the normal colonic epithelium.
- There is no dyplasia.
