It is composed of an admixture of mature adipocytes and fibroblast-like spindle cells in a myxoid stroma. Retroperitoneal atypical spindle cell lipomatous tumor are extremely rare only a single report in the literature reported. Herein we describe a case of a giant lipomatous tumor that was causing partial bowel obstruction. Successful excision with en block resection of the tumor, distal ureter and posterior wall of the bladder was achieved by teamwork between gastrointestinal surgeons and Urologist. The bladder defect was repaired, and left ureteric reimplantation was done. The patient made a good recovery with excellent progress. He has resumed his normal activities as a farmer.<\/jats:p>","DOI":"10.1093\/jscr\/rjad040","type":"journal-article","created":{"date-parts":[[2023,2,11]],"date-time":"2023-02-11T22:11:23Z","timestamp":1676153483000},"source":"Crossref","is-referenced-by-count":8,"title":["An extremely rare neoplasm \u2018atypical spindle cell pleomorphic lipomatous tumor\u2019: a case report"],"prefix":"10.1093","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5023-7749","authenticated-orcid":false,"given":"Paul William Itule","family":"Lugwaja","sequence":"first","affiliation":[{"name":"Muhimbili University of Health and Allied Science (MUHAS) Department of Surgery, , Upanga Street, Ilala, PO Box 65001 Dar es salaam, Tanzania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yona","family":"Ringo","sequence":"additional","affiliation":[{"name":"Muhimbili National Hospital Department of General Surgery, , Upanga Street, Ilala, PO Box 65000 Dar es salaam, Tanzania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Godfrey","family":"Mchele","sequence":"additional","affiliation":[{"name":"Muhimbili National Hospital Department of General Surgery, , Upanga Street, Ilala, PO Box 65000 Dar es salaam, Tanzania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Mtaturu","sequence":"additional","affiliation":[{"name":"Muhimbili National Hospital Department of Urology, , Upanga Street, Ilala, PO Box 65000 Dar es salaam, Tanzania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,2,11]]},"reference":[{"key":"2023021122110543300_ref1","doi-asserted-by":"crossref","first-page":"100450","DOI":"10.1016\/j.ijso.2022.100450","article-title":"Pleomorphic lipoma of the loin region;
