It occurs rarely in the foot and if occurs, the calcaneus and the metatarsals are commonly involved. We present a case of a young woman diagnosed with primary Ewing\u2019s sarcoma of the talus with local spread to adjacent tarsals and the ankle joint. Ewing\u2019s sarcoma of feet, if present with even a trivial suspicion of spread either locally or distant, makes limb salvage surgery difficult. So, the treatment with radical surgery or by combined chemotherapy and radiotherapy should be considered\u2014keeping in mind the complex anatomy of the foot and the difficulty in achieving tumour-free margins. Based on this experience, she underwent below-knee amputation. The patient received adjuvant chemotherapy and survived with a disease-free survival at the latest follow-up of 1\u2009year.<\/jats:p>","DOI":"10.1136\/bcr-2023-258243","type":"journal-article","created":{"date-parts":[[2023,12,7]],"date-time":"2023-12-07T19:17:12Z","timestamp":1701976632000},"page":"e258243","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Primary Ewing\u2019s sarcoma of the talus"],"prefix":"10.1136","volume":"16","author":[{"given":"Prabodh","family":"Kantiwal","sequence":"first","affiliation":[{"name":"Department of Orthopedics, All India Institute of Medical Sciences-Jodhpur, Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandeep Kumar","family":"Yadav","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, All India Institute of Medical Sciences-Jodhpur, Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aasma","family":"Nalwa","sequence":"additional","affiliation":[{"name":"Department of Pathology & Lab Medicine, All India Institute of Medical Sciences, Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2080-2612","authenticated-orcid":false,"given":"Rajesh Kumar","family":"Rajnish","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, All India Institute of Medical Sciences-Jodhpur, Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,12,7]]},"reference":[{"key":"2025082801131976000_16.12.e258243.1","doi-asserted-by":"crossref","first-page":"307","DOI":"10.1002\/jso.24817","article-title":"Management of primary malignant bone and soft tissue tumors of foot and ankle: is it worth salvaging?","volume":"117","author":"\u00d6zger","year":"2018","journal-title":"J Surg Oncol"},{"key":"2025082801131976000_16.12.e258243.2","doi-asserted-by":"crossref","first-page":"1008","DOI":"10.2106\/00004623-195335040-00022","article-title":"Ewing\u2019s tumor of the Talus (Astragalus) Simulating aseptic necrosis","volume":"35-A","author":"COHEN","year":"1953","journal-title":"J Bone Joint Surg Am"},{"key":"2025082801131976000_16.12.e258243.3","first-page":"17","article-title":"Diffuse Endothelioma of bone","volume":"21","author":"Ewing","year":"1921","journal-title":"Proc NYPathol Soc"},{"key":"2025082801131976000_16.12.e258243.4","doi-asserted-by":"crossref","first-page":"331","DOI":"10.2214\/ajr.144.2.331","article-title":"Radiographic appearance of Ewing sarcoma of the hands and feet: report from the intergroup Ewing sarcoma study","volume":"144","author":"Reinus","year":"1985","journal-title":"AJR Am J Roentgenol"},{"key":"2025082801131976000_16.12.e258243.5","doi-asserted-by":"crossref","first-page":"568","DOI":"10.1308\/rcsann.2017.0114","article-title":"Malignant bone tumours of the foot","volume":"99","author":"Yang","year":"2017","journal-title":"Ann R Coll Surg Engl"},{"key":"2025082801131976000_16.12.e258243.6","doi-asserted-by":"crossref","first-page":"492","DOI":"10.1097\/00000441-196511000-00002","article-title":"The clinical and Roentgen aspects of Ewing's sarcoma","volume":"250","author":"Falk","year":"1965","journal-title":"Am J Med Sci"},{"key":"2025082801131976000_16.12.e258243.7","first-page":"333","article-title":"Ewing's tumor of the Talus Misdiagnosed as Avascular necrosis.
