EMP of the larynx represents 0.04 to 0.45% of malignant tumors of the larynx. A male of 57 years old presented with hoarseness, dyspnea, and biphasic stridor of 2 months. The indirect laryngoscopy (IL) revealed severe edema of the posterior commissure and a polypoid mass in the right posterior lateral subglottic wall. A biopsy of the subglottic mass was performed by a direct laryngoscopy (DL). The histopathologic diagnosis was EMP CD138+, therefore radiotherapy was given at 54\u2009Gy in 30 sessions. The patient had an adequate postoperative clinical course and a new biopsy was performed having tumor-free margins. All laryngeal lesions should be biopsied prior to treatment to determine an accurate diagnosis to guide a proper management of the condition. Radiation therapy to the EMP is considered the treatment of choice, having local control rates of 80% to 100%. The subglottis is the least accessible area of view and the least frequent location of a laryngeal mass, nevertheless the otolaryngologist should always do a complete and systematic exam of the larynx when a tumor is suspected, to detect diagnoses such as a subglottic plasmacytoma.<\/jats:p>","DOI":"10.1155\/2012\/437264","type":"journal-article","created":{"date-parts":[[2012,10,4]],"date-time":"2012-10-04T17:04:56Z","timestamp":1349370296000},"page":"1-3","source":"Crossref","is-referenced-by-count":9,"title":["Extramedullary Plasmacytoma of the Larynx: A Case Report of Subglottic Localization"],"prefix":"10.1155","volume":"2012","author":[{"given":"Jaqueline","family":"Ram\u00edrez-Anguiano","sequence":"first","affiliation":[{"name":"Otolaryngology Head and Neck Surgery Service, Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n Salvador Zubir\u00e1n, Vasco de Quiroga 15, Tlalpan, 14000 Mexico City, DF, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugo","family":"Lara-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Otolaryngology Head and Neck Surgery Service, Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n Salvador Zubir\u00e1n, Vasco de Quiroga 15, Tlalpan, 14000 Mexico City, DF, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deborah","family":"Mart\u00ednez-Ba\u00f1os","sequence":"additional","affiliation":[{"name":"Hematology and Oncology Department, Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n Salvador Zubir\u00e1n, Vasco de Quiroga 15, Tlalpan, 14000 Mexico City, DF, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8925-8651","authenticated-orcid":true,"given":"Braulio","family":"Mart\u00ednez-Ben\u00edtez","sequence":"additional","affiliation":[{"name":"Clinical Pathology Department, Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n Salvador Zubir\u00e1n, Vasco de Quiroga 15, Tlalpan, 14000 Mexico City, DF, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"9","key":"1","doi-asserted-by":"crossref","first-page":"567","DOI":"10.1177\/014556130708600913","volume":"86","year":"2007","journal-title":"Ear, Nose and Throat Journal"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otorri.2010.04.001"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1378\/chest.120.4.1405"},{"issue":"3","key":"4","first-page":"225","volume":"36","year":"2002","journal-title":"Radiology and Oncology"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1002\/dc.1090"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-007-0289-x"},{"issue":"3","key":"8","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1007\/s11864-002-0015-2","volume":"3","year":"2002","journal-title":"Current Treatment Options in Oncology"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.21248"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/54563070"}],"container-title":["Case Reports in Otolaryngology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/criot\/2012\/437264.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criot\/2012\/437264.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criot\/2012\/437264.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,7,4]],"date-time":"2019-07-04T08:06:59Z","timestamp":1562227619000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/criot\/2012\/437264\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":9,"alternative-id":["437264","437264"],"URL":"https:\/\/doi.org\/10.1155\/2012\/437264","relation":{},"ISSN":["2090-6765","2090-6773"],"issn-type":[{"value":"2090-6765","type":"print"},{"value":"2090-6773","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
