Böbrek kökenli primer sarkomlar oldukça nadir görülen tümörlerdir. Böbrek tümörlerinin % 0,8-2,7'sini oluşturmaktadırlar. Yetmiş üç yaşında kadın, kliniğimize sağ böğür ağrısı şikâyeti ile başvurdu. Yapılan ultrasonografisinde sağ böbrek pelvis anteriorunda 7x4 cm'lik kitle tespit edildi ve tanı bilgisayarlı tomografi ile doğrulandı. Kitleden iğne biyopsisi yöntemi ile örnek alınarak incelendi. Sonuç malign tümör olarak rapor edildi. Bunun üzerine hastaya sağ radikal nefrektomi uygulandı. Radikal nefrektomi materyali patolojik inceleme sonucu “iyi diferansiye leiomyosarkom” olarak rapor edildi. Amerikan Birleşik Kanser Komitesi'nin (AJCC) yumuşak doku sarkomlarına yönelik evrelemesine göre bu vaka evre 1B olarak kabul edildi. Cerrahi tedavi sonrası adjuvan tedavi önerildi ancak hasta bu tedaviyi kabul etmedi. Postoperatif altı aylık takip süresince hastada klinik veya radyolojik progresyon tespit edilmedi.
