Margins were grossly uninvolved. Histopathology showed a moderately differentiated squamous cell carcinoma. Microscopic evaluation of margins was challenging, as the inferior osseous margin submitted en face showed spongiotic epithelium with mixed chronic and acute inflammation, representing a periapical cyst after correlation with the gross examination. Another section of the osseous margin showed a small non-atypical epithelial nest, consistent with an odontogenic epithelial rest. We wish to raise awareness of these diagnostic pitfalls as a bone margin with such epithelial foci could be misinterpreted as positive, with serious therapeutic consequences.<\/jats:p>","DOI":"10.1177\/1066896920905085","type":"journal-article","created":{"date-parts":[[2020,2,7]],"date-time":"2020-02-07T06:33:57Z","timestamp":1581057237000},"page":"507-509","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Periapical Cyst and Odontogenic Remnants on Osseous Mandibulectomy Margins: Two Diagnostic Pitfalls"],"prefix":"10.1177","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5444-0349","authenticated-orcid":false,"given":"Simon F.","family":"Roy","sequence":"first","affiliation":[{"name":"University of Montreal, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00e9mie","family":"Berdugo","sequence":"additional","affiliation":[{"name":"University of Montreal, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,2,7]]},"reference":[{"key":"bibr1-1066896920905085","doi-asserted-by":"publisher","DOI":"10.1007\/s10266-018-0397-7"},{"key":"bibr2-1066896920905085","doi-asserted-by":"publisher","DOI":"10.1007\/s10006-019-00816-8"},{"key":"bibr3-1066896920905085","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.2016.191"},{"key":"bibr4-1066896920905085","doi-asserted-by":"publisher","DOI":"10.1016\/j.path.2016.10.006"},{"key":"bibr5-1066896920905085","doi-asserted-by":"publisher","DOI":"10.1038\/labinvest.2016.85"}],"container-title":["International Journal of Surgical Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896920905085","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1066896920905085","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896920905085","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:21:09Z","timestamp":1777458069000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1066896920905085"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,2,7]]},"references-count":5,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2020,8]]}},"alternative-id":["10.1177\/1066896920905085"],"URL":"https:\/\/doi.org\/10.1177\/1066896920905085","relation":{},"ISSN":["1066-8969","1940-2465"],"issn-type":[{"value":"1066-8969","type":"print"},{"value":"1940-2465","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,2,7]]}}}
