The deposition of amyloid proteins can be systemic or localized, idiopathic or related to systemic diseases, mostly multiple myeloma or chronic inflammatory diseases. Localized head and neck amyloidosis is a rare entity, mainly involving the larynx. Given the rarity of the disease and the absence of a lasting follow-up protocol, there is no standard treatment defined for localized amyloidosis. We report a rare case of localized nasopharyngeal amyloidosis, treated with complete transoral resection and confirmed by histological examination.<\/jats:p>","DOI":"10.1177\/0145561320914432","type":"journal-article","created":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T02:38:16Z","timestamp":1585622296000},"page":"562-565","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["A Rare Nasopharyngeal Presentation of Amyloidosis"],"prefix":"10.1177","volume":"100","author":[{"given":"Erika","family":"Crosetti","sequence":"first","affiliation":[{"name":"Head and Neck Oncology Unit, Candiolo Cancer Institute, FPO\u2013IRCCS, Candiolo, Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4267-8066","authenticated-orcid":false,"given":"Andrea","family":"Manca","sequence":"additional","affiliation":[{"name":"Head and Neck Oncology Unit, Candiolo Cancer Institute, FPO\u2013IRCCS, Candiolo, Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Maldi","sequence":"additional","affiliation":[{"name":"Pathology Unit, Candiolo Cancer Institute, FPO \u2013 IRCCS, Candiolo, Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Succo","sequence":"additional","affiliation":[{"name":"Head and Neck Oncology Unit, Candiolo Cancer Institute, FPO\u2013IRCCS, Candiolo, Torino, Italy"},{"name":"Department of Oncology, University of Turin, Orbassano, Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,3,30]]},"reference":[{"key":"bibr1-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1080\/13506120500032196"},{"key":"bibr2-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2013.04.003"},{"key":"bibr3-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1080\/13506129.2016.1257986"},{"key":"bibr4-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1159\/000444206"},{"key":"bibr5-0145561320914432","doi-asserted-by":"publisher","DOI":"10.3109\/13506129.2014.964858"},{"key":"bibr6-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1016\/j.oraloncology.2005.09.010"},{"key":"bibr7-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198006123022403"},{"key":"bibr8-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198006053022305"},{"key":"bibr9-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1016\/0037-198X(86)90027-1"},{"key":"bibr10-0145561320914432","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2006.08.009"},{"key":"bibr11-0145561320914432","doi-asserted-by":"crossref","unstructured":"Sakagiannis G, Giotakis E, Thompson LDR.
