Abstract

Background: Osseous metaplasia is considered as a response to insults such as chronic inflammation or mucin extravasation in colorectal polyps. Case report: we report two cases of osseous metaplasia in juvenile (retention) polyps as incidental histopathological findings in a case of rectal juvenile polyposis and a patient with solitary rectal juvenile polyp. Conclusion: Osseous metaplasia can occur in colorectal juvenile polyps and is considered a probable response to mucin extravasation and/or chronic inflammation. The clinical and prognostic significance of osseous metaplasia in these polyps is unknown. © 2020 Taylor & Francis Group, LLC.
