Early diagnosis is particularly challenging due to the tumour\u2019s location in the retroperitoneal space, which provides ample room for expansion. Symptoms typically manifest only when the tumor reaches a substantial size or invades adjacent organs. We report a case of a 61-year-old woman who underwent surgical resection for a well-differentiated liposarcoma. Computed tomography scan revealed that the mass invaded the left perirenal fascia and displaced the descending colon, pancreas, and duodenum. Complete resection of tumour masses was performed, and we opted to preserve the kidney due to no visible renal parenchymal tumour invasion. The management of retroperitoneal perirenal liposarcoma typically entails the implementation of an R0 resection. If a tumor extends into an adjacent tissue, one must consider the benefits of achieving clear surgical margins versus the risks of medical issues and reduced quality of life.<\/jats:p>","DOI":"10.1093\/jscr\/rjag319","type":"journal-article","created":{"date-parts":[[2026,4,15]],"date-time":"2026-04-15T11:39:15Z","timestamp":1776253155000},"source":"Crossref","is-referenced-by-count":0,"title":["Report on a case of giant retroperitoneal perirenal liposarcoma with kidney preservation"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5732-8208","authenticated-orcid":false,"given":"Lujie","family":"Shi","sequence":"first","affiliation":[{"name":"Department of General Surgery, Xindu District People's Hospital of Chengdu , Sichuan ,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Liao","sequence":"additional","affiliation":[{"name":"Precision Medicine Research Center, West China Hospital, Sichuan University , Chengdu ,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Xindu District People's Hospital of Chengdu , Sichuan ,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,4,28]]},"reference":[{"key":"2026042813245591300_ref1","doi-asserted-by":"publisher","first-page":"102013","DOI":"10.1016\/j.ctrv.2020.102013","article-title":"A review of retroperitoneal liposarcoma genomics","volume":"86","author":"Tyler","year":"2020","journal-title":"Cancer Treat Rev"},{"key":"2026042813245591300_ref2","doi-asserted-by":"publisher","first-page":"88","DOI":"10.1177\/000313481307900216","article-title":"Surgical management of incidental renal tumor during excision of retroperitoneal liposarcoma and osteogenic sarcoma","volume":"79","author":"Frank","year":"2013","journal-title":"Am Surgeon"},{"key":"2026042813245591300_ref3","doi-asserted-by":"publisher","first-page":"e59","DOI":"10.1016\/j.amjsurg.2008.07.061","article-title":"Huge liposarcoma of the left retroperitoneum","volume":"197","author":"Goertz","year":"2009","journal-title":"Am J Surg"},{"key":"2026042813245591300_ref4","doi-asserted-by":"publisher","first-page":"483154","DOI":"10.1155\/2011\/483154","article-title":"Liposarcoma: molecular genetics and therapeutics","volume":"2011","author":"Conyers","year":"2011","journal-title":"Sarcoma."},{"key":"2026042813245591300_ref5","doi-asserted-by":"publisher","first-page":"7873","DOI":"10.1245\/s10434-021-09654-z","article-title":"Management of Primary Retroperitoneal Sarcoma (RPS) in the adult: an updated consensus approach from the transatlantic Australasian RPS working group","volume":"28","author":"Swallow","year":"2021","journal-title":"Ann Surg Oncol"},{"key":"2026042813245591300_ref6","doi-asserted-by":"publisher","DOI":"10.1097\/01.sla.0000086542.11899.38","article-title":"Histologic subtype and margin of resection predict pattern of recurrence and survival for retroperitoneal liposarcoma","volume":"238","author":"Singer","year":"2003","journal-title":"Ann Surg"},{"key":"2026042813245591300_ref7","first-page":"20","article-title":"Combined operations by retroperitoneal liposarcomas","volume":"6","author":"Stilidi","year":"2013","journal-title":"Khirurgiia"},{"key":"2026042813245591300_ref8","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1002\/jso.20265","article-title":"Retroperitoneal sarcoma: 25 years of experience with aggressive surgical treatment at the Institute of Oncology","volume":"91","author":"Erzen","year":"2005","journal-title":"Ljubljana J SURG ONCOL"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/4\/rjag319\/68180482\/rjag319.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/4\/rjag319\/68180482\/rjag319.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T17:25:02Z","timestamp":1777397102000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjag319\/8664203"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,1]]},"references-count":8,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2026,4,1]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjag319","relation":{},"ISSN":["2042-8812"],"issn-type":[{"value":"2042-8812","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,4]]},"published":{"date-parts":[[2026,4,1]]},"article-number":"rjag319"}}
