Very few cases of chondrosarcomas arising in parotid gland have been reported and none with intracranial extension. We report a case of a female presenting with a parotid swelling and a mass in external auditory canal with extradural extension to posterior cranial fossa. With a preoperative fine needle aspiration diagnosis of pleomorphic adenoma, it was excised and the histopathology came out to be low-grade myxoid chondrosarcoma. She has not received any adjuvant chemoradiotherapy and there is no evidence of recurrence at months.<\/jats:p>","DOI":"10.1136\/bcr-2019-231643","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T05:37:19Z","timestamp":1575351439000},"page":"e231643","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["A rare case of chondrosarcoma arising in parotid with extension to lateral skull base"],"prefix":"10.1136","volume":"12","author":[{"given":"Sidharth","family":"Pradhan","sequence":"first","affiliation":[{"name":"ENT, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saurav","family":"Sarkar","sequence":"additional","affiliation":[{"name":"ENT and Head Neck Surgery, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mukund N","family":"Sable","sequence":"additional","affiliation":[{"name":"Department of Pathology, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pradipta Kumar","family":"Parida","sequence":"additional","affiliation":[{"name":"ENT and Head Neck Surgery, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,12,2]]},"reference":[{"key":"2025082702595463000_12.12.e231643.1","doi-asserted-by":"publisher","DOI":"10.1159\/000055721"},{"key":"2025082702595463000_12.12.e231643.2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0347(200007)22:4<408::AID-HED15>3.0.CO;2-H"},{"key":"2025082702595463000_12.12.e231643.3","first-page":"69","article-title":"Unusual mesenchymal and mixed tumors of the salivary gland","volume":"119","author":"Bocklage","year":"1995","journal-title":"Arch Pathol Lab Med"},{"key":"2025082702595463000_12.12.e231643.4","doi-asserted-by":"crossref","first-page":"1301","DOI":"10.1288\/00005537-199012000-00010","article-title":"Chondrosarcoma of the head and neck","volume":"100","author":"Burkey","year":"1990","journal-title":"Laryngoscope"},{"key":"2025082702595463000_12.12.e231643.5","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197708)40:2<818::AID-CNCR2820400234>3.0.CO;2-B"},{"key":"2025082702595463000_12.12.e231643.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9610(70)80006-X"},{"key":"2025082702595463000_12.12.e231643.7","doi-asserted-by":"crossref","first-page":"1539","DOI":"10.1288\/00005537-198412000-00001","article-title":"Chondrosarcoma of the head and neck","volume":"94","author":"Finn","year":"1984","journal-title":"Laryngoscope"},{"key":"2025082702595463000_12.12.e231643.8","doi-asserted-by":"crossref","first-page":"725","DOI":"10.1017\/S0022215107006081","article-title":"Chondrosarcomas of the skull base and temporal bone","volume":"121","author":"Lustig","year":"2007","journal-title":"J Laryngol Otol"},{"key":"2025082702595463000_12.12.e231643.9","doi-asserted-by":"crossref","first-page":"E310","DOI":"10.1002\/lary.25802","article-title":"Atypical cartilaginous tumor\/chondrosarcoma, grade 1, of the mastoid in three family members: a new entity","volume":"126","author":"Frisch","year":"2016","journal-title":"Laryngoscope"},{"key":"2025082702595463000_12.12.e231643.10","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2006.11.037"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-231643","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T10:00:05Z","timestamp":1756288805000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-231643"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12]]},"references-count":10,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2019,12,2]]},"published-print":{"date-parts":[[2019,12]]}},"alternative-id":["10.1136\/bcr-2019-231643"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-231643","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,12]]}}}
