Lymphadenopathy is a side effect of SARS-CoV-2 vaccine. We report a rare example of Kikuchi disease in the cervical lymph nodes after SARS-CoV-2 vaccination. A 41-year-old man complained of a swollen neck and fever 9 days after the first dose of SARS-CoV-2 mRNA-1273 vaccine. Computed tomography revealed enlarged cervical lymph nodes. Fine needle aspiration and resection were performed, and the clinicopathological diagnosis was consistent with Kikuchi disease. Histologically, the resected lymph nodes lost their polarity, and many histiocytes were aggregated with karyorrhectic nuclear debris and apoptosis. SARS-CoV-2 positive cells were small lymphocytes detected by immunohistochemistry. This is the first report that demonstrated SARS-CoV-2 expression in Kikuchi disease post-SARS-CoV-2 vaccination.<\/jats:p>","DOI":"10.1177\/10668969231212428","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T00:59:05Z","timestamp":1700441945000},"page":"1123-1128","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Kikuchi Disease After SARS-CoV-2 Vaccination: A Case Report With Immunohistochemical Analyses"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3511-760X","authenticated-orcid":false,"given":"Yuichiro","family":"Hamamoto","sequence":"first","affiliation":[{"name":"Department of Diagnostic Pathology, Kinki Central Hospital, Itami, Hyogo, Japan"},{"name":"Osaka University Graduate School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michihiro","family":"Kawamura","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideo","family":"Mori","sequence":"additional","affiliation":[{"name":"Osaka Habikino Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Uchida","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiro","family":"Hiramatsu","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiaki","family":"Katori","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hinako","family":"Asai","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroko","family":"Kawasaki","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taishi","family":"Minamino","sequence":"additional","affiliation":[{"name":"Osaka General Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michiko","family":"Hashimoto","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin-ichi","family":"Nakatsuka","sequence":"additional","affiliation":[{"name":"Department of Pathology, Yao Tokushukai General Hospital, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyotaro","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Kinki Central Hospital, Itami, Hyogo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,11,19]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/cyt.13221"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2018-0219-RA"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.3390\/biomedicines10051010"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2022-252030"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2022-250601"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/21645515.2022.2071080"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.3390\/vaccines9111251"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.idcr.2021.e01253"},{"issue":"4","key":"e_1_3_3_10_2","article-title":"Kikuchi-Fujimoto\u2019s disease or histiocytic necrotizing lymphadenitis following mRNA COVID-19 vaccination: A rare case","volume":"14","author":"Daghri S","year":"2022","unstructured":"Daghri S, Belmoufid N, Rami A, Bouzidi Al, Bouanani AN.
