Polyps are classified histopathologically as neoplastic and non-neoplastic. Here, we present one such rare case of a middle-childhood boy who presented with complaints of bleeding per-rectum and revealed a 1.5\u2009cm long rectal polyp. Histopathological examination revealed an osseous change in the rectal polyp. A detailed literature review of reported cases of benign rectal polyps with osseous metaplasia was conducted and consolidated all postulated theories of pathogenesis. This case report shows an interesting incidental finding of osseous metaplasia of the rectal polyp.<\/jats:p>","DOI":"10.1136\/bcr-2023-254819","type":"journal-article","created":{"date-parts":[[2023,9,26]],"date-time":"2023-09-26T13:06:12Z","timestamp":1695733572000},"page":"e254819","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Osseous metaplasia in a rectal polyp"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6730-5886","authenticated-orcid":false,"given":"Ananyan","family":"Sampath","sequence":"first","affiliation":[{"name":"All India Institute of Medical Science, Bhopal, Madhya Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hemalata","family":"Panwar","sequence":"additional","affiliation":[{"name":"Department of Pathology, All India Institute of Medical Science, Bhopal, Madhya Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7350-9228","authenticated-orcid":false,"given":"Neelkamal N A","family":"Kapoor","sequence":"additional","affiliation":[{"name":"Department of Pathology, All India Institute of Medical Science, Bhopal, Madhya Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0119-1577","authenticated-orcid":false,"given":"Pramod Kumar","family":"Sharma","sequence":"additional","affiliation":[{"name":"Pediatric Surgery, All India Institute of Medical Science, Bhopal, Madhya Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,9,26]]},"reference":[{"key":"2025082801202692000_16.9.e254819.1","doi-asserted-by":"crossref","unstructured":"Jayadevan R . n.d.
