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.
