LMS has an insidious presentation that is often misdiagnosed as a benign lesion. This report outlines an innocuous case of paratesticular leiomyosarcoma while focusing on the diagnosis and treatment paratesticular LMS. We report the case of an 84-year-old male who presented with a painless left scrotal swelling of 5\u2009days\u2019 duration. Imaging and tumor markers suggested a paratesticular mass suspicious for malignancy. Surgical excision revealed a F\u00e9d\u00e9ration Nationale des Centres de Lutte Contre le Cancer Grade 2 leiomyosarcoma arising from the scrotal soft tissue, confirmed by positive smooth muscle markers on immunohistochemistry. Postoperative imaging demonstrated no recurrence at 8\u2009months. This case highlights the diagnostic challenge of paratesticular leiomyosarcoma and the importance of surgical resection and careful follow-up for optimal patient outcomes.<\/jats:p>","DOI":"10.1177\/23247096261420891","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T04:44:06Z","timestamp":1772081046000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A Rare Paratesticular Leiomyosarcoma Presenting as a Painless Scrotal Mass in an Elderly Patient: A Case Report"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8500-4032","authenticated-orcid":false,"given":"Marvin A.","family":"Simpkins","sequence":"first","affiliation":[{"name":"Joan C.
