We report a 33-year-old woman with ovarian DSRCT presenting as a pelvic mass and peritoneal metastases. Histopathology revealed small round cell nests within desmoplastic stroma, exhibiting atypical architectural patterns (single-file, follicular-like cystic, microcystic, and solid). Immunohistochemistry demonstrated coexpression of epithelial (pan-keratin) and mesenchymal markers (vimentin, desmin), while molecular analysis confirmed the\n                    <jats:italic toggle=\"yes\">EWSR1<\/jats:italic>\n                    ::\n                    <jats:italic toggle=\"yes\">WT1<\/jats:italic>\n                    gene fusion. Despite multimodal therapy, the patient died 24 months after surgery. A review of 23 ovarian DSRCTs proposed a classification: ovarian-dominant and extraovarian-dominant subtypes. Ovarian-dominant patients showed significantly prolonged median survival (24 vs 10 months,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.026), underscoring the prognostic relevance of anatomical classification. Ovarian DSRCT poses diagnostic challenges due to histomorphological mimicry of common malignancies. Although this subclassification may aid prognostication, multicenter validation is warranted.\n                  <\/jats:p>","DOI":"10.1177\/10668969251412899","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T09:37:00Z","timestamp":1773394620000},"page":"1235-1240","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Desmoplastic Small Round Cell Tumor of the Ovary: A Case Report With Atypical Morphologic Features and Literature Review"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7602-7440","authenticated-orcid":false,"given":"Feng","family":"Shi","sequence":"first","affiliation":[{"name":"Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaomin","family":"Feng","sequence":"additional","affiliation":[{"name":"Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning","family":"Qian","sequence":"additional","affiliation":[{"name":"Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2783-2929","authenticated-orcid":false,"given":"Yun","family":"Gu","sequence":"additional","affiliation":[{"name":"Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,3,13]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.suronc.2019.04.002"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000021337"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.18.20179"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.3109\/15513818909022347"},{"issue":"4","key":"e_1_3_3_6_2","first-page":"415","article-title":"Changing incidence and survival of desmoplastic small round cell tumor in the USA","volume":"35","author":"Waqar SHB","year":"2022","unstructured":"Waqar SHB, Ali H.
