This tumor predominantly involves the mandible, though the maxilla can also be involved in some cases. The involvement of maxillary sinuses, however, has been previously reported in only 8 case reports English literature. These patients chiefly presented with nasal obstruction along with epistaxis or proptosis in rare cases. However, a primary presentation as nasal polyp is unheard of. We present a rare case of calcifying epithelial odontogenic tumor presenting as a nasal polyp, posing a diagnostic difficulty.<\/jats:p>","DOI":"10.1177\/1066896916644782","type":"journal-article","created":{"date-parts":[[2016,4,21]],"date-time":"2016-04-21T01:35:28Z","timestamp":1461202528000},"page":"568-572","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Pindborg Tumor Presenting as a Nasal Polyp"],"prefix":"10.1177","volume":"24","author":[{"given":"Suvradeep","family":"Mitra","sequence":"first","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gurwinder","family":"Kaur","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ritambhra","family":"Nada","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satyawati","family":"Mohindra","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,7,28]]},"reference":[{"key":"bibr1-1066896916644782","first-page":"205","volume":"36","author":"Muller D","year":"2012","journal-title":"Coll Antropol"},{"key":"bibr2-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1016\/j.jobcr.2014.03.002"},{"key":"bibr3-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1016\/S1368-8375(99)00061-5"},{"key":"bibr4-1066896916644782","doi-asserted-by":"publisher","DOI":"10.4103\/0973-029X.102520"},{"key":"bibr5-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1965.5"},{"key":"bibr6-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0714.2007.00567.x"},{"key":"bibr7-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1016\/0278-2391(92)90237-T"},{"key":"bibr8-1066896916644782","first-page":"e38","volume":"59","author":"da Rosa MR","year":"2011","journal-title":"Gen Dent"},{"key":"bibr9-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1016\/j.tripleo.2005.12.019"},{"key":"bibr10-1066896916644782","doi-asserted-by":"publisher","DOI":"10.12968\/denu.2009.36.6.350"},{"key":"bibr11-1066896916644782","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(68)90281-8"}],"container-title":["International Journal of Surgical Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896916644782","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1066896916644782","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896916644782","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:21:01Z","timestamp":1777458061000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1066896916644782"}},"subtitle":["Immunohistology and Ultrastructural Features of a Rare Case, With Review of the Literature"],"short-title":[],"issued":{"date-parts":[[2016,7,28]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2016,9]]}},"alternative-id":["10.1177\/1066896916644782"],"URL":"https:\/\/doi.org\/10.1177\/1066896916644782","relation":{},"ISSN":["1066-8969","1940-2465"],"issn-type":[{"value":"1066-8969","type":"print"},{"value":"1940-2465","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,7,28]]}}}
