It falls within the spectrum of neoplastic diseases known as Ewing\u2019s family of tumours, typically observed in osseous tissues. A woman in her 40s, experiencing symptoms of leucorrhoea and transvaginal bleeding that commenced 3\u2009months before her consultation, was referred to our gynaecological oncology clinic with a preliminary diagnosis of ovarian teratoma. A colposcopy procedure was conducted unveiling a complete loss of cervical anatomy with friable and malodorous tissue. Pelvic ultrasound identified a lesion of uncertain origin in the cervix, suggestive of malignancy. Histopathological assessment of cervical biopsy specimens confirmed the presence of a small, round, blue cell neoplasm consistent with Ewing sarcoma. She underwent chemotherapy and pelvic radiotherapy, achieving complete remission 9\u2009months after diagnosis, without experiencing any systemic adverse effects or sequelae.<\/jats:p>","DOI":"10.1136\/bcr-2023-257912","type":"journal-article","created":{"date-parts":[[2024,3,21]],"date-time":"2024-03-21T13:00:44Z","timestamp":1711026044000},"page":"e257912","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Ewing sarcoma of the cervix: an unusual site of presentation"],"prefix":"10.1136","volume":"17","author":[{"given":"Jes\u00fas Guillermo","family":"Hern\u00e1ndez-Garc\u00eda","sequence":"first","affiliation":[{"name":"Internal Medicine, Hospital Juarez de Mexico, Mexico, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis Jos\u00e9","family":"Pinto Garc\u00eda","sequence":"additional","affiliation":[{"name":"Internal Medicine, Hospital Juarez de Mexico, Mexico, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osvaldo Alexis","family":"March\u00e9 Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Internal Medicine, Hospital Juarez de Mexico, Mexico, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0739-0449","authenticated-orcid":false,"given":"Juan Daniel","family":"Diaz-Garcia","sequence":"additional","affiliation":[{"name":"Internal Medicine, Hospital Juarez de Mexico, Mexico, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,3,21]]},"reference":[{"key":"2025082703335412000_17.3.e257912.1","article-title":"Incidence of Ewing\u2019s sarcoma in different age groups, their associated features, and its correlation with primary care interval","volume":"13","author":"Khan","year":"2021","journal-title":"Cureus"},{"key":"2025082703335412000_17.3.e257912.2","doi-asserted-by":"crossref","DOI":"10.1186\/1746-1596-1-30","article-title":"Uncommon Sarcomas of the uterine Cervix: A review of selected entities","volume":"1","author":"Fadare","year":"2006","journal-title":"Diagn Pathol"},{"key":"2025082703335412000_17.3.e257912.3","unstructured":"Durer S , Shaikh H .
