Data collection included clinical presentation, radiographic, laboratory results, and pathologic findings.\n                    <jats:bold>Results:<\/jats:bold>\n                    A total of 12 patients had laryngeal amyloidosis and true vocal cord was the most common location. Protein electrophoresis detected monoclonal protein in 10% (1\/10) of patients tested. Two patients had hematopoietic disorder (2\/12, 17%) and another patient had a peptide profile consistent with amyloid transthyretin (ATTR) detected by mass spectrometry. Twelve patients showed amyloidosis in the oral cavity with 75% involving the tongue. Monoclonal protein was found in 89% of cases tested. Nine patients (9\/12, 75%) had systematic involvement including 6 with hematopoietic malignancy and 3 with biopsy-confirmed systemic light chain amyloidosis. Compared to the laryngeal amyloidosis, amyloid deposition in oral cavity had a significant higher association with systematic disease (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; .01). Pharyngeal amyloidosis was seen in 7 patients. Three of 6 patients tested (3\/6, 50%) were found to have biopsy-confirmed hematopoietic malignancy.\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Laryngeal amyloidosis is mostly a localized disease. Amyloidosis involving oral cavity is associated with significantly higher risk of systematic involvement which warrants a comprehensive laboratory, radiographic, and pathologic workup. There is limited data about pharynx amyloidosis. Oropharynx and hypopharynx amyloidosis appear to be more likely associated with underlying hematologic malignancy compared to nasopharynx involvement.\n                  <\/jats:p>","DOI":"10.1177\/01455613231189144","type":"journal-article","created":{"date-parts":[[2023,7,29]],"date-time":"2023-07-29T01:59:30Z","timestamp":1690595970000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Amyloid Deposition in the Upper Aerodigestive Tract, A Single Institute Experience"],"prefix":"10.1177","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5930-4365","authenticated-orcid":false,"given":"Tieying","family":"Hou","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asma","family":"Abu-Salah","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar W.","family":"Cummings","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stacey","family":"Halum","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Indiana University School of Medicine, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1833-4642","authenticated-orcid":false,"given":"Hector","family":"Mesa","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongwei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,7,28]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1080\/13506129.2020.1835263"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1159\/000506696"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.3880092"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/lary.29320"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.3109\/13506129.2012.723073"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215117000780"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-018-9956-x"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348949210100910"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2002.123106"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12070-007-0101-7"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2019.1680864"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05730-z"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/019459989210600410"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200312000-00007"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348940411300913"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200410000-00012"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.oraloncology.2005.09.010"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/lary.26846"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1177\/00034894211042772"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000016830"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2009-07-230722"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2020.06.029"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348948409300418"},{"key":"e_1_3_2_25_2","first-page":"338","article-title":"Amyloidosis of the oral cavity: report of five cases","volume":"12","author":"Madani M","year":"1991","unstructured":"Madani M, Harwick RD, Chen SY, Miller AS.
