According to the extent of the lesion, it can be divided into systemic amyloidosis and localized amyloidosis. Amyloidosis originating in the larynx accounts for approximately 0.5% to 1.0% of benign lesions of the larynx; such lesions are relatively rare and mostly localized. Nasopharyngeal amyloidosis combined with laryngeal amyloidosis is even rarer. We herein present a case involving a patient with amyloidosis in the nasopharynx and larynx who presented with a foreign body sensation and hoarseness in the pharynx. Electronic fiber laryngoscopy revealed a smooth neoplasm in the left nasopharynx and left vocal cord. The patient underwent surgical treatment, and the postoperative pathologic examination results suggested amyloidosis. Special staining performed using Congo red and crystal violet was positive, confirming amyloidosis. The patient recovered after surgery, and no recurrence was present at the 3- and 6-month follow-ups.<\/jats:p>","DOI":"10.1177\/03000605221144151","type":"journal-article","created":{"date-parts":[[2022,12,21]],"date-time":"2022-12-21T00:30:05Z","timestamp":1671582605000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Amyloidosis in the nasopharynx and larynx: a case report"],"prefix":"10.1177","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0312-5496","authenticated-orcid":false,"given":"Yu","family":"Feng","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Liaocheng People\u2019s Hospital, Liaocheng, China"},{"name":"Shandong First Medical University (Shandong Academy of Medical Sciences), Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maocai","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Liaocheng People\u2019s Hospital, Liaocheng, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5109-9093","authenticated-orcid":false,"given":"Dong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Liaocheng People\u2019s Hospital, Liaocheng, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongya","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Liaocheng Dongchangfu People's Hospital, Liaocheng, China"},{"name":"Shandong First Medical University (Shandong Academy of Medical Sciences), Taian, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lianqing","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Liaocheng People\u2019s Hospital, Liaocheng, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lili","family":"Gong","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Liaocheng People\u2019s Hospital, Liaocheng, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"bibr1-03000605221144151","doi-asserted-by":"publisher","DOI":"10.3390\/molecules26154611"},{"key":"bibr2-03000605221144151","volume-title":"Handbuch der pathologischen anatomie","author":"von Rokitansky KF","year":"1842"},{"key":"bibr3-03000605221144151","doi-asserted-by":"publisher","DOI":"10.1007\/BF01930815"},{"key":"bibr4-03000605221144151","doi-asserted-by":"publisher","DOI":"10.1080\/13506129.2022.2035354"},{"key":"bibr5-03000605221144151","doi-asserted-by":"publisher","DOI":"10.1016\/j.blre.2019.100636"},{"key":"bibr6-03000605221144151","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-018-9956-x"},{"key":"bibr7-03000605221144151","doi-asserted-by":"publisher","DOI":"10.3389\/fsurg.2021.774469"},{"key":"bibr8-03000605221144151","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000016830"},{"key":"bibr9-03000605221144151","first-page":"12","volume":"31","author":"Ying L","year":"2010","journal-title":"Journal of Medical Forum"},{"issue":"4","key":"bibr10-03000605221144151","first-page":"395","author":"Han B","year":"2007","journal-title":"Journal of Harbin Medical University"},{"key":"bibr11-03000605221144151","doi-asserted-by":"publisher","DOI":"10.1002\/lary.29061"}],"container-title":["Journal of International Medical Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/03000605221144151","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/03000605221144151","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/03000605221144151","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:49:47Z","timestamp":1777459787000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/03000605221144151"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,12]]},"references-count":11,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2022,12]]}},"alternative-id":["10.1177\/03000605221144151"],"URL":"https:\/\/doi.org\/10.1177\/03000605221144151","relation":{},"ISSN":["0300-0605","1473-2300"],"issn-type":[{"value":"0300-0605","type":"print"},{"value":"1473-2300","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,12]]},"article-number":"03000605221144151"}}
