Abstract
Primary liposarcoma of the spermatic cord is rare, and preoperative diagnosis is difficult. We report a rare case of well-differentiated liposarcoma in 65-year-old man. The patient’s chief complaint was painless enlargement of a mass in the right inguinal area that had persisted for about two months. The main component of the mass was wrapped around the spermatic cord and several components were around the testis. Ultrasonography of the main component showed mixed echogenicity. CT showed an ovoid fat-containing nodule and several other fat-density masses surrounding the testis. The mass was surgically removed, along with the right testis and spermatic cord. A pathological examination showed a well-differentiated liposarcoma of the right spermatic cord and testis.

Summary
Sarcomas of the genitourinary tract account for nearly 2% of all urologic tumors. The spermatic cord is the most commonly involved urologic site, and accounts for approximately 30% of all genitourinary sarcomas [1,2,3]. Liposarcomas are malignant neoplasms of adipose tissue arising from primitive mesenchymal cells. In almost 70% of cases, they are located in the extremities and the retroperitoneum. The spermatic cord is a rare site of origin, accounting for only 3% - 7% of all liposarcoma [1,4]. We describe a case of liposarcoma in the testis and spermatic cord and present a literature review of spermatic cord liposarcoma
