The three types of plasmacytoma, according to clinical features and morphological characteristics, include solitary bone plasmacytoma, extramedullary plasmacytoma (EMP), and multiple myeloma (MM). Although EMP of the head and neck region accounts for approximately 3% of all plasma cell tumors, the involvement of both paranasal sinuses is extremely rare. Herein, we describe a rare case of EMP involving both maxillary sinuses in a 73-year-old male patient who had achieved complete remission from MM following chemotherapy 2 years ago. The EMP was treated successfully with radiotherapy.<\/jats:p>","DOI":"10.18787\/jr.2023.00032","type":"journal-article","created":{"date-parts":[[2023,11,27]],"date-time":"2023-11-27T23:45:28Z","timestamp":1701128728000},"page":"173-176","update-policy":"https:\/\/doi.org\/10.18787\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Case of Extramedullary Plasmacytoma in Both Maxillary Sinuses"],"prefix":"10.18787","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2025-2769","authenticated-orcid":true,"given":"Myeonggu","family":"Seo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9301-6957","authenticated-orcid":true,"given":"Ji-Hwan","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8436-5722","authenticated-orcid":true,"given":"Sung-Dong","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3848-1781","authenticated-orcid":true,"given":"Kyung Un","family":"Choi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4381-6996","authenticated-orcid":true,"given":"Kyu-Sup","family":"Cho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7989","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1053\/adpa.2002.33458"},{"key":"ref2","first-page":"452305","volume-title":"Relapse of multiple myeloma presenting as extramedullary plasmacytomas in multiple organs","author":"K\u00f6se","year":"2015"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3109\/10428194.2012.740562"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1038\/s41408-021-00527-y"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1056\/nejmra041875"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1186\/s12885-020-06870-w"},{"key":"ref7","first-page":"1632","volume-title":"CT and MR imaging of solitary extramedullary plasmacytoma of the nasal tract","author":"Ching","year":"2002"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.5812\/iranjradiol.111764"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/00125480-200107000-00003"},{"key":"ref10","first-page":"645","volume-title":"Detection of clonality with kappa and lambda immunohistochemical analysis in cutaneous plasmacytomas","author":"Bayer-Garner","year":"2004"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.5045\/br.2020.s008"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1200\/jco.2009.26.4465"},{"key":"ref13","first-page":"45","volume-title":"Extramedullary disease in multiple myeloma: a systematic literature review","author":"Blad\u00e9","year":"2022"}],"container-title":["Journal of Rhinology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/j-rhinology.org\/upload\/pdf\/jr-2023-00032.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/j-rhinology.org\/journal\/view.php?doi=10.18787\/jr.2023.00032","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/j-rhinology.org\/upload\/pdf\/jr-2023-00032.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,4]],"date-time":"2023-12-04T04:19:47Z","timestamp":1701663587000},"score":1,"resource":{"primary":{"URL":"http:\/\/j-rhinology.org\/journal\/view.php?doi=10.18787\/jr.2023.00032"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,11,30]]},"references-count":13,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2023,11]]}},"URL":"https:\/\/doi.org\/10.18787\/jr.2023.00032","relation":{},"ISSN":["1229-1498","2384-4361"],"issn-type":[{"value":"1229-1498","type":"print"},{"value":"2384-4361","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,11,30]]},"assertion":[{"value":"2023-04-09","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-05-17","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-11-27","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-11-30","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
