Unaware of her pregnancy status, she underwent concurrent radiotherapy and chemotherapy for extraosseous Ewing\u2019s sarcoma. During the workup following treatment of Ewing\u2019s sarcoma, she underwent ultrasonographic examination, which showed a single, live intrauterine gestation. The pregnancy was terminated due to cytotoxic effects of the chemoradiation. Treatment of Ewing\u2019s sarcoma involves a combination of surgery, chemotherapy and radiotherapy. In pregnant women with Ewing\u2019s sarcoma, a multidisciplinary approach is needed to diagnose and treat the condition. Any form of teratogenic drug or radiation exposure during the first trimester and early second trimester can have potential damage on the fetus.<\/jats:p>","DOI":"10.1136\/bcr-2024-263727","type":"journal-article","created":{"date-parts":[[2025,5,11]],"date-time":"2025-05-11T07:25:11Z","timestamp":1746948311000},"page":"e263727","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Ewing\u2019s
