Recently, we encountered a case of solitary malignant schwannoma in the choana and posterior nasal septum. Malignant schwannoma has not been previously reported in these locations. A 53-year-old man, who was immunologically healthy and showed no abnormal dermatological lesions, presented with a polypoid mass in the right nasal cavity and underwent endoscopic mass excision. The mass originated from the choana and the posterior portion of the right nasal septum. This mass was confirmed as a malignant schwannoma on histological examination and immunohistochemical staining. After endoscopic excision, postoperative adjuvant radiotherapy was administered, and there was no recurrence at 1 year after treatment. This case suggests that a solitary malignant schwannoma should be considered in the differential diagnosis of a mass in the posterior nasal cavity.<\/jats:p>","DOI":"10.1155\/2014\/202910","type":"journal-article","created":{"date-parts":[[2014,9,9]],"date-time":"2014-09-09T21:00:35Z","timestamp":1410296435000},"page":"1-4","source":"Crossref","is-referenced-by-count":4,"title":["A Solitary Malignant Schwannoma in the Choana and Nasal Septum"],"prefix":"10.1155","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0454-4510","authenticated-orcid":true,"given":"Eun Jung","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Gangnam Severance Hospital, Yonsei University College of Medicine, 211 Eonju-ro, Gangnam-gu, Seoul 135-720, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kee Jae","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Gangnam Severance Hospital, Yonsei University College of Medicine, 211 Eonju-ro, Gangnam-gu, Seoul 135-720, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeon Suk","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Gangnam Severance Hospital, Yonsei University College of Medicine, 211 Eonju-ro, Gangnam-gu, Seoul 135-720, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyung-Su","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Gangnam Severance Hospital, Yonsei University College of Medicine, 211 Eonju-ro, Gangnam-gu, Seoul 135-720, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"4","key":"1","first-page":"251","volume":"16","year":"1995","journal-title":"American Journal of Otolaryngology\u2014Head and Neck Medicine and Surgery"},{"issue":"9","key":"2","doi-asserted-by":"crossref","first-page":"1196","DOI":"10.5858\/2003-127-1196-SOTSTA","volume":"127","year":"2003","journal-title":"Archives of Pathology and Laboratory Medicine"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/66348609"},{"issue":"1","key":"4","first-page":"33","volume":"114","year":"1993","journal-title":"Revue de Laryngologie Otologie Rhinologie"},{"issue":"8","key":"5","doi-asserted-by":"crossref","first-page":"634","DOI":"10.1177\/014556130308200822","volume":"82","year":"2003","journal-title":"Ear, Nose & Throat Journal"},{"issue":"4","key":"6","first-page":"489","volume":"35","year":"2006","journal-title":"African Journal of Medicine and Medical Sciences"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1590\/S1808-86942012000400026"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-197003000-00016"},{"issue":"5","key":"9","doi-asserted-by":"crossref","first-page":"362","DOI":"10.1177\/014556139307200513","volume":"72","year":"1993","journal-title":"Ear, Nose and Throat Journal"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(96)70148-1"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1186\/1758-3284-4-26"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.7150\/jca.4179"},{"issue":"4","key":"13","first-page":"929","volume":"27","year":"2006","journal-title":"The American Journal of Neuroradiology"}],"container-title":["Case Reports in Otolaryngology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/criot\/2014\/202910.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criot\/2014\/202910.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criot\/2014\/202910.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,16]],"date-time":"2022-04-16T17:49:22Z","timestamp":1650131362000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/criot\/2014\/202910\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":13,"alternative-id":["202910","202910"],"URL":"https:\/\/doi.org\/10.1155\/2014\/202910","relation":{},"ISSN":["2090-6765","2090-6773"],"issn-type":[{"value":"2090-6765","type":"print"},{"value":"2090-6773","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
