She also had constitutional symptoms with significant weight loss. On physical examination, she appeared cachexic, her left knee was swollen and tender. MRI of the left knee showed a soft tissue swelling extending into the knee joint. Left knee synovial fluid showed small round cells. Histopathology results were compatible with Ewing\u2019s sarcoma. Due to the delay in seeking medical advice, she succumbed to the disease 1\u2009week after the diagnosis was made. Soft tissue\/bone tumour causes monoarthritis is not common. A careful history taking, physical examination and investigations should be done in order to identify a sinister cause of monoarthritis such as Ewing\u2019s sarcoma. Early treatment should be initiated to ensure a better outcome.<\/jats:p>","DOI":"10.1136\/bcr-2019-232193","type":"journal-article","created":{"date-parts":[[2020,3,20]],"date-time":"2020-03-20T05:54:28Z","timestamp":1584683668000},"page":"e232193","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Delayed diagnosis of Ewing\u2019s sarcoma in a young patient presented with left knee monoarthritis"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0752-2154","authenticated-orcid":false,"given":"Chong Hong","family":"Lim","sequence":"first","affiliation":[{"name":"Rheumatology Unit, Department of Internal Medicine, Hospital Sultanah Bahiyah, Alor Setar, Kedah Darul Aman, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuen Han","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Hospital Sultanah Bahiyah, Alor Setar, Kedah Darul Aman, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Radzi","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Department of Internal Medicine, Hospital Sultanah Bahiyah, Alor Setar, Kedah Darul Aman, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,3,19]]},"reference":[{"key":"2025082710452161000_13.3.e232193.1","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.24388"},{"key":"2025082710452161000_13.3.e232193.2","doi-asserted-by":"publisher","DOI":"10.1111\/os.12239"},{"key":"2025082710452161000_13.3.e232193.3","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2007-0291"},{"key":"2025082710452161000_13.3.e232193.4","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780291008"},{"key":"2025082710452161000_13.3.e232193.5","doi-asserted-by":"publisher","DOI":"10.1007\/s12098-010-0131-0"},{"key":"2025082710452161000_13.3.e232193.6","doi-asserted-by":"crossref","first-page":"192","DOI":"10.5858\/2007-131-192-SRCTOB","article-title":"Small round cell tumors of bone","volume":"131","author":"Hameed","year":"2007","journal-title":"Arch Pathol Lab Med"},{"key":"2025082710452161000_13.3.e232193.7","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-014-0687-z"},{"key":"2025082710452161000_13.3.e232193.8","doi-asserted-by":"crossref","first-page":"272","DOI":"10.1089\/jayao.2018.0136","article-title":"Management of sarcoma in adolescents and young adults: an Australian population-based study","volume":"8","author":"White","year":"2019","journal-title":"J Adolesc Young Adult Oncol"},{"key":"2025082710452161000_13.3.e232193.9","doi-asserted-by":"crossref","first-page":"603","DOI":"10.1016\/j.suronc.2018.07.016","article-title":"Prognostic factors for survival in Ewing sarcoma: a systematic review","volume":"27","author":"Bosma","year":"2018","journal-title":"Surg Oncol"},{"key":"2025082710452161000_13.3.e232193.10","doi-asserted-by":"crossref","first-page":"1254","DOI":"10.12659\/MSM.913338","article-title":"Surgical resection of primary Ewing's sarcoma of bone improves overall survival in patients presenting with metastasis","volume":"25","author":"Ren","year":"2019","journal-title":"Med Sci Monit"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-232193","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T17:45:27Z","timestamp":1756316727000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-232193"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3]]},"references-count":10,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2020,3,19]]},"published-print":{"date-parts":[[2020,3]]}},"alternative-id":["10.1136\/bcr-2019-232193"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-232193","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2020,3]]}}}
