Retroperitoneal liposarcoma presenting as spermatic cord tumor

A well-differentiated liposarcoma of the retroperitoneum and spermatic cord, contiguous through the inguinal canal, presented clinically as a scrotal mass. Radical orchiectomy was performed with removal of the spermatic cord tumor. The retroperitoneal portion was not discovered until one month postoperatively when a computerized tomographic scan of the abdomen was done. A recommendation is made for preoperative evaluation of the retroperitoneal space prior to extirpation of supratesticular spermatic cord masses.
