説明

A 52-year-old man was referred to our hospital for evaluation of painless right scrotal swelling persisting for 3 months. Palpation detected swelling and induration centered on the head of the upper epididymis, and ultrasonography revealed a blood-filled nodular mass at the same site continuing to the spermatic cord. No abnormalities were observed in the bilateral testes. Blood tests were negative for tumor markers such as α fetoprotein and human chorionic gonadotropin-β. Right radical inguinal orchiectomy was performed, and the pathological diagnosis was dedifferentiated liposarcoma of the spermatic cord. Although the spermatic cord stump was negative, the peri-spermatic cord stump, which had an exfoliated surface, was positive. No residual tumor was found on magnetic resonance imaging, but the tumor was suspected to remain. Thus, after approximately 1 month, the tissue around the spermatic cord was resected. Eight months after the initial operation, no recurrence was observed. Here, we report a case of dedifferentiated liposarcoma of the spermatic cord, which is relatively rare, and review the related literature.
