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.

摘要

背景

骨化生被认为是对诸如慢性炎症或结直肠息肉中粘蛋白外渗等损伤的反应。

结论

骨化生可发生在结直肠幼年息肉中，被认为可能是对粘蛋白外渗和/或慢性炎症的反应。这些息肉中骨化生的临床和预后意义尚不清楚。
