Abstract
We described the morphological, histochemical and immunohistochemical findings of a polyp detected in the left colon (splenic flexure) in which the diagnosis was atypical hyperplastic polyp. The description is focused on the capability of a hyperplastic polyp to evolve into adenomatous tissue through different modalities.
