It accounts for less than 1 case per million, typically affecting adolescents and young adults. We report a rare case of pleural EES in a 42\u2010year\u2010old woman presenting with chest pain and low\u2010grade fever persisting for one month. Physical examination showed decreased breath sounds in the right lung base on auscultation. Ultrasound demonstrated right\u2010sided pleural effusion, an unusual manifestation of EES that can hinder accurate diagnosis. CT scans identified multiple pulmonary nodules, further confirmed by thoracoscopy. Biopsy established the diagnosis of EES. The patient was subsequently treated with multi\u2010agent VAC\/IE chemotherapy. Despite initiation of systemic therapy, the disease followed an aggressive course, and the patient succumbed during follow\u2010up. We also review existing literature to highlight clinical, pathological, and radiological features of pleural EES, aiming to expand knowledge of this rare presentation.<\/jats:p>","DOI":"10.1002\/rcr2.70498","type":"journal-article","created":{"date-parts":[[2026,2,4]],"date-time":"2026-02-04T16:44:55Z","timestamp":1770223495000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Adult\u2010Onset Primary Pleura Ewing Sarcoma With Recurrent Pleural Effusion: A Case Report and Literature Review"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-3072-4536","authenticated-orcid":false,"given":"Hamza Khan","family":"Khattak","sequence":"first","affiliation":[{"name":"Department of Medicine Khyber Medical College  Peshawar Khyber Pakhtunkhwa Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6733-8773","authenticated-orcid":false,"given":"Laiba","family":"Malik","sequence":"additional","affiliation":[{"name":"Department of Medicine Khyber Medical College  Peshawar Khyber Pakhtunkhwa Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4070-4449","authenticated-orcid":false,"given":"Zmarak Ahmed","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Medicine Khyber Medical College  Peshawar Khyber Pakhtunkhwa Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0245-8692","authenticated-orcid":false,"given":"Mahliqa","family":"Kirmani","sequence":"additional","affiliation":[{"name":"Department of Medicine Khyber Medical College  Peshawar Khyber Pakhtunkhwa Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saadia","family":"Ashraf","sequence":"additional","affiliation":[{"name":"Department of Pulmonology Khyber Teaching Hospital  Peshawar Khyber Pakhtunkhwa Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6821-5653","authenticated-orcid":false,"given":"Zaryab","family":"Bacha","sequence":"additional","affiliation":[{"name":"Department of Medicine Khyber Medical College  Peshawar Khyber Pakhtunkhwa Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8208-0689","authenticated-orcid":false,"given":"Kamil Ahmad","family":"Kamil","sequence":"additional","affiliation":[{"name":"Internal Medicine Department Mirwais Regional Hospital  Kandahar Afghanistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,4]]},"reference":[{"key":"e_1_2_9_2_1","volume-title":"StatPearls","author":"Durer S.","year":"2025"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1148\/92.7.1501"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/08880010902855581"},{"key":"e_1_2_9_5_1","first-page":"683","article-title":"Extraskeletal Ewing's Sarcoma.
