Ethmoid sinus localization is exceptionally rare, with only a few cases documented in the literature. We present the case of a 34-year-old female who developed progressive right-sided nasal obstruction and epistaxis, with imaging revealing a locally invasive ethmoidal mass. Histopathological and immunohistochemical analysis confirmed a diagnosis of poorly differentiated synovial sarcoma. Incidentally, renal and intracranial findings suggested a possible underlying tuberous sclerosis complex. The patient was managed with a multimodal approach, including neoadjuvant chemotherapy (ifosfamide and doxorubicin), radiotherapy, and endoscopic surgical resection. Postoperative imaging demonstrated complete tumor clearance, and histology confirmed no residual malignancy. This case highlights the diagnostic and therapeutic challenges posed by ethmoidal synovial sarcoma and underscores the importance of individualized, multidisciplinary care, while also presenting an association with tuberous sclerosis that warrants further exploration.<\/jats:p>","DOI":"10.1177\/01455613251377977","type":"journal-article","created":{"date-parts":[[2025,9,28]],"date-time":"2025-09-28T11:31:58Z","timestamp":1759059118000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Primary Synovial Sarcoma of the Ethmoid Sinus in a Young Female: A Rare Case Associated With Tuberous Sclerosis Complex"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6514-5206","authenticated-orcid":false,"given":"Elias Edward","family":"Lahham","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology, Augusta Victoria Hospital, East Jerusalem, Palestine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marwan","family":"Qubaja","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Al-Quds University, Abu Dis, West Bank, Palestine"},{"name":"Department of Pathology, Augusta Victoria Hospital, East Jerusalem, Palestine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahmeh","family":"Deek","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Al-Quds University, Abu Dis, West Bank, Palestine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad","family":"Abuzir","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Al-Quds University, Abu Dis, West Bank, Palestine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahmoud","family":"Ramahi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Augusta Victoria Hospital, East Jerusalem, Palestine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ibrahem","family":"Eid","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Augusta Victoria Hospital, East Jerusalem, Palestine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,9,28]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.7248\/jjrhi.47.109"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2020.05.092"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.20564"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamaoto.2016.0384"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200211000-00013"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/rjae579"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1158\/2159-8290.CD-14-1246"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215114002151"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.anorl.2017.10.007"},{"issue":"3","key":"e_1_3_3_11_2","article-title":"Synovial sarcoma of ethmoidal sinus","volume":"7","author":"Dhiman S","year":"2021","unstructured":"Dhiman S, Negi S, Moudgil S, Thakur JS, Azad RK.
