We report a rare pseudo-malignant paranasal extranodal Rosai\u2013Dorfman disease. A 69-year-old-man presented nasal bleeding and nasal obstruction. Paranasal mass was detected in the left nasal cavity and computed tomography (CT) findings are the sphenoid sinus, maxillary sinus, and ethmoid sinus were involved with inconstant bone thickening, however, no bone destruction was detected. Magnetic resonance imaging scans show iso-intensity signal in T1-weighed image and T2-weighed image. Positron emission tomography\/CT fluorodeoxyglucose (FDG) uptake in posterior ethmoid sinus and sphenoid sinus, bilateral cervical lymph node, clavicle, and sternum. Based on the above results, we considered malignant lymphoma and performed a biopsy. After pathological examination, a diagnosis of Rosai\u2013Dorfman disease was established.<\/jats:p>","DOI":"10.1177\/01455613231195422","type":"journal-article","created":{"date-parts":[[2023,8,26]],"date-time":"2023-08-26T06:29:10Z","timestamp":1693031350000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A Rare Case of Pseudo-Malignant Paranasal Extranodal Rosai\u2013Dorfman Disease"],"prefix":"10.1177","volume":"104","author":[{"given":"Koichi","family":"Tamura","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6861-1700","authenticated-orcid":false,"given":"Takeshi","family":"Tsuda","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuya","family":"Takeda","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sho","family":"Obata","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masako","family":"Kurashige","sequence":"additional","affiliation":[{"name":"Department of Pathology, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichi","family":"Morii","sequence":"additional","affiliation":[{"name":"Department of Pathology, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidenori","family":"Inohara","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,8,26]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.175.2.1750465"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/alr.21836"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/md.0000000000031759"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/rlu.0000000000003327"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0347(200010)22:7<722::aid-hed13>3.0.co;2-0"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v10.i17.5869"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1177\/0145561320973783"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.2019.219626"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/107327481402100408"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.5334\/jbsr.2896"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1177\/01455613221079500"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1097\/rlu.0000000000003014"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/rlu.0000000000003911"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.5581\/1516-8484.20110083"}],"container-title":["Ear, Nose &amp;
