Paratesticular liposarcoma of the spermatic cord: a case report and review of the literature.

Spermatic cord liposarcoma is a rare medical condition and liposarcomas are most commonly found in the retroperitoneum, in the extremities and less often in the head and the neck area. The spermatic cord is a rare site of origin, accounting for about 3-7% of all liposarcomas. We report a case of liposarcoma of spermatic cord. A 62-year-old male patient presented with a painless right inguinal mass. MRI (magnetic resonance imaging) showed a fatty mass in the right inguinoscrotal region, and was interpreted as an inguinal hernia containing omentum protruding into scrotum. The mass was removed with right testis and spermatic cord. The surgical margins were negative. Histopathological examination and immunohistochemistry revealed a well-differentiated liposarcoma. In this article, we discuss the clinical behavior of the spermatic cord liposarcoma and currently recommended treatment of the spermatic cord liposarcoma by reviewing the literature. In conclusion, spermatic cord liposarcoma are rare neoplasm that present as firm, slow-growing palpable paratesticular masses and the surgical treatment should include a wide resection around the inguinal canal, with removal of the spermatic cord and the surrounding soft tissue deep to the internal inguinal ring.
