A 32 year-old physician, who had rectal bleeding.
A large mass between the second and third rectal valve is appreciated. The histopathologic study reveled tubular adenoma.

The "hyperplastic polyp" is considered a benign lesion with no malignant potential, whereas "serrated adenoma" is a precursor of adenocarcinoma. The morphologic complexity
of the serrated adenoma varies from being clearly adenomatous to being difficult to distinguish from hyperplastic polyp, which creates a need for more detailed morphologic analysis of all serrated polyps.
