Clinical symptoms are nonspecific, posing challenges for early diagnosis. In this report, we present two cases of middle\u2010aged women presenting with abnormal vaginal bleeding. Neither human papillomavirus typing nor blood tests showed specific abnormalities. Ultrasound examination identified uneven hypoechoic lesions with well\u2010defined borders in the cervix, and color Doppler imaging showed punctate linear blood flow signals within the lesions. Histopathological biopsies confirmed the diagnosis of primary ES of the uterine cervix. Both patients achieved favorable prognoses following a combined treatment of surgery and chemotherapy. This study highlights the value of ultrasound imaging in aiding the timely diagnosis of this rare malignancy.<\/jats:p>","DOI":"10.1002\/jcu.70050","type":"journal-article","created":{"date-parts":[[2025,9,13]],"date-time":"2025-09-13T09:04:13Z","timestamp":1757754253000},"page":"490-498","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Diagnostic Value of Ultrasound in Primary Cervical Ewing's Sarcoma: Two Case Reports and Literature Review"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-9280-8893","authenticated-orcid":false,"given":"Ziwei","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Ultrasound Sichuan University, West China Second University Hospital  Chengdu Sichuan China"},{"name":"Key Laboratory of Obstetric &amp; Gynecologic and Pediatric Diseases and Birth Defects of Ministry of Education  Chengdu Sichuan China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7757-1683","authenticated-orcid":false,"given":"Hong","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Ultrasound Sichuan University, West China Second University Hospital  Chengdu Sichuan China"},{"name":"Key Laboratory of Obstetric &amp; Gynecologic and Pediatric Diseases and Birth Defects of Ministry of Education  Chengdu Sichuan China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,13]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3892\/ol.2021.12615"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2016-217461"},{"issue":"1","key":"e_1_2_9_4_1","first-page":"203","article-title":"Extraosseous Ewing's Sarcoma: Pictorial Review of Imaging Findings, Differential Diagnosis, and Pathologic Correlation","volume":"31","author":"Alexander A.","year":"2021","journal-title":"Indian Journal of Radiology and Imaging"},{"key":"e_1_2_9_5_1","first-page":"285","article-title":"Primitive Neuroectodermal Tumor of the Cervix Uteri: A Case Report","volume":"48","author":"Al\u2010Nueimy W.
