DLBCL\u2010NOS which primarily arises from maxillary sinus is rare and hard to diagnose due to unique anatomy. Here, we present a case of DLBCL\u2010NOS that developed in the left maxillary sinus of a 72\u2010year\u2010old male, who presented with severe toothache that resembled acute pulpitis. The lesion was diagnosed and treated based on radiographs, histological, immunohistological examinations, and PET\u2010CT analysis. Despite its rare incidence, DLBCL\u2010NOS should still be included in differential diagnoses to rule out malignancy in cases of endodontic disease.<\/jats:p>","DOI":"10.1155\/2022\/8875832","type":"journal-article","created":{"date-parts":[[2022,4,7]],"date-time":"2022-04-07T16:20:09Z","timestamp":1649348409000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Primary Extra Nodal Diffuse Large B\u2010Cell Lymphoma of the Maxillary Sinus with Symptoms of Acute Pulpitis"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4629-6356","authenticated-orcid":false,"given":"Jian-tong","family":"Cui","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8459-961X","authenticated-orcid":false,"given":"Shao-qing","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3203-7495","authenticated-orcid":false,"given":"Hui-xia","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,4,7]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.anndiagpath.2018.09.014"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pathol.2017.09.006"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.21147\/j.issn.1000-9604.2019.01.10"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.3290\/j.qi.a43666"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/ger.12470"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2017.04.001"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/17474086.2018.1506326"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2014.10.008"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.adaj.2018.07.016"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2020.08.023"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05544-z"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2016-218686"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.beha.2018.07.014"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-13150-4_11"},{"key":"e_1_2_6_15_2","first-page":"34","article-title":"Extranodal large B cell lymphoma of the anterior maxilla.
