They typically manifest in the head and neck region, with a preference for the maxillofacial skeleton, particularly the mandible and maxilla. However, chondrosarcoma of the sinonasal tract is exceptionally rare, and only few cases have been reported. Case Presentation: This report details the case of a 43-year-old woman who incidentally discovered chondrosarcoma in the maxillary and ethmoid sinuses with nasal extension. Subsequently, the patient underwent surgery via a paralatero-nasal approach with adjuvant radiotherapy. The aim of this study was to describe the clinical findings, management, and outcome of sinonasal tract chondrosarcoma. Conclusions: The primary treatment for chondrosarcomas remains surgery, with a transnasal endoscopic approach offering a viable option for complete resection in select cases.<\/jats:p>","DOI":"10.1177\/01455613241249028","type":"journal-article","created":{"date-parts":[[2024,4,24]],"date-time":"2024-04-24T06:33:15Z","timestamp":1713940395000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Chondrosarcoma of the Nasal Cavity and Paranasal Sinuses: A Rare Entity"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5034-1151","authenticated-orcid":false,"given":"El Omri","family":"Malika","sequence":"first","affiliation":[{"name":"Department of Ear, Nose, Throat and Head and Neck Surgery, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5784-4681","authenticated-orcid":false,"given":"Marwa","family":"Ben Njima","sequence":"additional","affiliation":[{"name":"Department of Ear, Nose, Throat and Head and Neck Surgery, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bellakhdher","family":"Mouna","sequence":"additional","affiliation":[{"name":"Department of Ear, Nose, Throat and Head and Neck Surgery, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nfikha","family":"Zeineb","sequence":"additional","affiliation":[{"name":"Pathology Department, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kemani","family":"Wassim","sequence":"additional","affiliation":[{"name":"Department of Ear, Nose, Throat and Head and Neck Surgery, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sriha","family":"Badreddine","sequence":"additional","affiliation":[{"name":"Pathology Department, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdelkefi","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Department of Ear, Nose, Throat and Head and Neck Surgery, Farhat Hached University Hospital, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,4,24]]},"reference":[{"key":"bibr1-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1097\/WNO.0000000000001130"},{"key":"bibr2-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-012-1521-3"},{"key":"bibr3-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1055\/s-2002-35003"},{"key":"bibr4-01455613241249028","doi-asserted-by":"publisher","DOI":"10.11604\/pamj.2014.19.165.4643"},{"key":"bibr5-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200305000-00004"},{"key":"bibr6-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1007\/BF02967829"},{"key":"bibr7-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0000000000002634"},{"key":"bibr8-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1258\/0022215001906174"},{"key":"bibr9-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1053\/j.sult.2008.10.013"},{"key":"bibr10-01455613241249028","doi-asserted-by":"publisher","DOI":"10.1002\/alr.21162"},{"issue":"6","key":"bibr11-01455613241249028","doi-asserted-by":"crossref","first-page":"889","DOI":"10.1093\/neuonc\/nou347","volume":"17","author":"Sahgal A","year":"2015","journal-title":"Neuro Oncol"},{"key":"bibr12-01455613241249028","doi-asserted-by":"publisher","DOI":"10.12890\/2020_001933"}],"container-title":["Ear, Nose &amp;
