While it can manifest in various anatomical locations, its occurrence in the nasopharynx is particularly uncommon with only 10 reported cases in the English literature. This case report describes a 45-year-old woman who complained of persistent neck swelling, nasal obstruction, and left ear fullness. Imaging showed a nasopharyngeal process and cervical lymphadenopathy. Biopsies confirmed FDCS. Treatment included chemotherapy and radiation, resulting in a favorable outcome with no recurrence during 2 years of follow-up.<\/jats:p>","DOI":"10.1177\/01455613241270506","type":"journal-article","created":{"date-parts":[[2024,8,28]],"date-time":"2024-08-28T01:56:30Z","timestamp":1724810190000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Nasopharyngeal Follicular Dendritic Cell Sarcoma: Diagnostic Challenges and Therapeutic Management"],"prefix":"10.1177","author":[{"given":"Monia","family":"Ghammam","sequence":"first","affiliation":[{"name":"Department of ENT and Cervical Surgery, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9189-3160","authenticated-orcid":false,"given":"Jihene","family":"Houas","sequence":"additional","affiliation":[{"name":"Department of ENT and Cervical Surgery, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heyfa","family":"Belhadj-Miled","sequence":"additional","affiliation":[{"name":"Department of ENT and Cervical Surgery, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarra","family":"Yacoub","sequence":"additional","affiliation":[{"name":"Pathology Department, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Selma","family":"Chaieb","sequence":"additional","affiliation":[{"name":"Pathology Department, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mouna","family":"Bellakhdher","sequence":"additional","affiliation":[{"name":"Department of ENT and Cervical Surgery, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Abdelkefi","sequence":"additional","affiliation":[{"name":"Department of ENT and Cervical Surgery, Farhat Hached Hospital, Medicine University, Sousse, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,8,27]]},"reference":[{"issue":"3","key":"bibr1-01455613241270506","first-page":"562","volume":"122","author":"Monda L","year":"1986","journal-title":"Am J Pathol"},{"key":"bibr2-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2011-01-293050"},{"key":"bibr3-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1007\/s004280050168"},{"key":"bibr4-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2001.01134.x"},{"key":"bibr5-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.3880489"},{"key":"bibr6-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1159\/000325817"},{"key":"bibr7-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.20852"},{"key":"bibr8-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2007.08.005"},{"key":"bibr9-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1309\/AJCP7U8YISBUAVNW"},{"key":"bibr10-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2011.06.024"},{"key":"bibr11-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1177\/03000605221097662"},{"key":"bibr12-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1080\/10428194.2023.2297939"},{"key":"bibr13-01455613241270506","doi-asserted-by":"publisher","DOI":"10.1186\/s13000-024-01444-x"}],"container-title":["Ear, Nose &amp; Throat Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/01455613241270506","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/01455613241270506","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/01455613241270506","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T18:35:21Z","timestamp":1777401321000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/01455613241270506"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,8,27]]},"references-count":13,"alternative-id":["10.1177\/01455613241270506"],"URL":"https:\/\/doi.org\/10.1177\/01455613241270506","relation":{},"ISSN":["0145-5613","1942-7522"],"issn-type":[{"value":"0145-5613","type":"print"},{"value":"1942-7522","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,8,27]]},"article-number":"01455613241270506"}}
