Upper gastrointestinal imaging showed a 12-cm tumor with a stalk arising from the esophageal entrance, extending to the middle intrathoracic esophagus, with a normal surface mucosa. Endoscopic ultrasound-fine needle aspiration biopsy showed that the nuclei of tumors cells were positive for murine double minute (MDM) and weakly positive for cyclin-dependent kinase 4 (CDK4). We diagnosed the tumor as the esophageal dedifferentiated liposarcoma, and planed tumor resection via the cervical approach. The tumor was successfully resected and the postoperative course was uneventful.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>This case report highlights the use of tumor resection via the cervical approach as a good option for esophageal liposarcoma.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40792-024-01990-y","type":"journal-article","created":{"date-parts":[[2024,9,19]],"date-time":"2024-09-19T08:02:28Z","timestamp":1726732948000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Esophageal dedifferentiated liposarcoma resected by the cervical approach: a case report"],"prefix":"10.1186","volume":"10","author":[{"given":"Kazuki","family":"Omachi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4028-1137","authenticated-orcid":false,"given":"Keisuke","family":"Kosumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takumi","family":"Tanizaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tasuku","family":"Toihata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaaki","family":"Iwatsuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshifumi","family":"Baba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuji","family":"Miyamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoya","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideo","family":"Baba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,8,28]]},"reference":[{"key":"1990_CR1","volume-title":"Enzinger and Weiss\u2019s soft tissue tumors","author":"JR Goldblum","year":"2019","unstructured":"Goldblum JR, Weiss SW, Folpe AL.
