Because it is uncommon and has nonspecific clinical features, it can be challenging to diagnose, making up less than 1% of all kidney tumours. Adults frequently exhibit it, with a slight preference for females in some instances that have been reported. A male in his early 60s with a history of abdominal pain for the previous 2\u2009months is presented here with a case of leiomyosarcoma of the kidney. While adjuvant medications like chemotherapy and radiation therapy have little effect, surgical resection with clear margins remains the main treatment option. There is a considerable chance of recurrence, so long-term monitoring is necessary.<\/jats:p>","DOI":"10.1136\/bcr-2025-266171","type":"journal-article","created":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T21:30:16Z","timestamp":1751405416000},"page":"e266171","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Primary renal leiomyosarcoma"],"prefix":"10.1136","volume":"18","author":[{"given":"Samikshya","family":"Thapa","sequence":"first","affiliation":[{"name":"Pathology and Laboratory Medicine, All India Institute of Medical Sciences - Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akanksha","family":"Gupta","sequence":"additional","affiliation":[{"name":"Pathology and Laboratory Medicine, All India Institute of Medical Sciences - Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vikas Kumar","family":"Panwar","sequence":"additional","affiliation":[{"name":"Urology, AIIMS Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5136-7254","authenticated-orcid":false,"given":"Ravi Hari","family":"Phulware","sequence":"additional","affiliation":[{"name":"Pathology and Laboratory Medicine, All India Institute of Medical Sciences - Rishikesh, Rishikesh, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,7,1]]},"reference":[{"key":"2025082711082778000_18.7.e266171.1","article-title":"The WHO 2022 Classification of Renal Neoplasms (5th Edition): Salient Updates","volume":"16","author":"Goswami","year":"2024","journal-title":"Cureus"},{"key":"2025082711082778000_18.7.e266171.2","doi-asserted-by":"crossref","first-page":"826","DOI":"10.1016\/j.avsg.2010.02.039","article-title":"Surgical challenges in the treatment of leiomyosarcoma of the inferior vena cava: analysis of two cases and brief review of the literature","volume":"24","author":"Kyriazi","year":"2010","journal-title":"Ann Vasc Surg"},{"key":"2025082711082778000_18.7.e266171.3","doi-asserted-by":"crossref","first-page":"241","DOI":"10.4103\/0019-509X.52962","article-title":"A case of leiomyosarcoma of kidney clinically and radiologically misdiagnosed as renal cell carcinoma","volume":"46","author":"Choudhury","year":"2009","journal-title":"Indian J Cancer"},{"key":"2025082711082778000_18.7.e266171.4","doi-asserted-by":"crossref","first-page":"1186","DOI":"10.4103\/jcrt.JCRT_107_19","article-title":"Primary leiomyosarcoma kidney - A rare entity with a diagnostic challenge","volume":"18","author":"Chaudhary","year":"2022","journal-title":"J Cancer Res Ther"},{"key":"2025082711082778000_18.7.e266171.5","first-page":"3435","article-title":"The comparative survival of renal leiomyosarcoma","volume":"14","author":"Kendal","year":"2007","journal-title":"Can J Urol"},{"key":"2025082711082778000_18.7.e266171.6","article-title":"Renal Leiomyosarcoma: Unraveling the Mysteries of a Rare Malignancy","volume":"15","author":"Poombal","year":"2023","journal-title":"Cureus"},{"key":"2025082711082778000_18.7.e266171.7","doi-asserted-by":"publisher","DOI":"10.1043\/1543-2165(2006)130[1448:GOSTSR]2.0.CO;2"},{"key":"2025082711082778000_18.7.e266171.8","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200402000-00004"},{"key":"2025082711082778000_18.7.e266171.9","article-title":"Primary leiomyosarcoma of the kidney","volume":"2010","author":"Venkatesh","year":"2010","journal-title":"Patholog Res Int"},{"key":"2025082711082778000_18.7.e266171.10","doi-asserted-by":"crossref","first-page":"E87","DOI":"10.5489\/cuaj.11159","article-title":"Renal leiomyoma: Case report and literature review","volume":"6","author":"Brunocilla","year":"2012","journal-title":"Can Urol Assoc J"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-266171","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T18:08:36Z","timestamp":1756318116000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-266171"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7]]},"references-count":10,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2025,7,1]]},"published-print":{"date-parts":[[2025,7]]}},"alternative-id":["10.1136\/bcr-2025-266171"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-266171","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2025,7]]}}}
