Following surgical excision together with a radical orchidectomy, the histological diagnosis was of a paratesticular dedifferentiated liposarcoma. Radiological staging showed no metastatic disease. Six months later the patient presented with a new left scrotal lump, which was felt to be separate from the testis. Owing to the previous history of a liposarcoma and indeterminate ultrasound findings, this was surgically excised without orchidectomy. Histological analysis showed this to be an angiolipoma. The patient remained on clinical and radiological surveillance. Paratesticular tumours are rare neoplasms and liposarcomas of the spermatic cord only represent 7% of these lesions. Any link between lipomatous tumours and liposarcomas remains controversial and is still under investigation. This is the first case to report a paratesticular liposarcoma and a contralateral angiolipoma in the same patient.<\/jats:p>","DOI":"10.1136\/bcr-2015-212078","type":"journal-article","created":{"date-parts":[[2015,10,5]],"date-time":"2015-10-05T07:48:05Z","timestamp":1444031285000},"page":"bcr2015212078","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Paratesticular liposarcoma and contralateral angiolipoma in a 60-year-old patient"],"prefix":"10.1136","volume":"2015","author":[{"given":"Michelle","family":"Christodoulidou","sequence":"first","affiliation":[{"name":"Department of Urology, University College London Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pramit","family":"Khetrapal","sequence":"additional","affiliation":[{"name":"Department of Histopathology, University College London Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lilian","family":"Edmunds","sequence":"additional","affiliation":[{"name":"Department of Histopathology, Royal National Orthopaedic Hospital, Middlesex, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asif","family":"Muneer","sequence":"additional","affiliation":[{"name":"Department of Urology, University College London Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,10,5]]},"reference":[{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjps.2011.08.004"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.2","doi-asserted-by":"publisher","DOI":"10.2298\/VSP1307695V"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.3","doi-asserted-by":"publisher","DOI":"10.1186\/1757-1626-3-27"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.4","doi-asserted-by":"publisher","DOI":"10.1097\/00005392-199501000-00055"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-4295(96)00545-6"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.6","doi-asserted-by":"publisher","DOI":"10.1159\/000189681"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.1993.tb16033.x"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.8","first-page":"563","article-title":"Distinction between lipoma and liposarcoma by MDM2 alterations: a case report of simultaneously occurring tumors and review of the literature","volume":"197","author":"Boltze","year":"2001","journal-title":"Pathol Res Pract"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.1969.tb11893.x"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.10","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(195209)5:5<975::AID-CNCR2820050513>3.0.CO;2-Y"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.11","doi-asserted-by":"publisher","DOI":"10.1054\/bjoc.1999.1090"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.12","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1081\/CNV-50432","article-title":"Differential gene expression in liposarcoma, lipoma, and adipose tissue","volume":"23","author":"Skubitz","year":"2005","journal-title":"Cancer Invest"},{"key":"2025082704074185000_2015.oct05_1.bcr2015212078.13","doi-asserted-by":"publisher","DOI":"10.1007\/BF00311652"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2015-212078","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T11:07:48Z","timestamp":1756292868000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2015-212078"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,10,5]]},"references-count":13,"alternative-id":["10.1136\/bcr-2015-212078"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2015-212078","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2015,10,5]]}}}
