Hyperplastic polyp of the duodenum
Benign serrated polyps are commonly found in the colorectum but have rarely been described in other parts of the gastrointestinal tract. Hyperplastic polyps or sessile serrated polyps in the colorectum can be associated. (21733555)
In a study, no patient met the criteria for serrated polyposis. (21733555)
Although probably rare and of uncertain malignant potential, duodenal hyperplastic polyp should be considered in the differential diagnosis of benign duodenal polyp.
The histologic appearance of the benign serrated polyps of the duodenum is similar to microvesicular hyperplastic polyp in the colorectum.
