抄録: | Liposarcomas are most commonly found in the extremities, in the retroperitoneum and, less often, in the head and neck area. The spermatic cord is a rare site of origin, accounting for about 4-7% of all liposarcomas. We report a case of dedifferentiated liposarcoma of the spermatic cord. A 51-year-old man was referred to our hospital for a painless hard mass in the left inguinal region. Abdominal computed tomography showed a left spermatic cord mass measuring 70 mm in diameter. We performed left high orchiectomy with resection of the mass. Immunohistochemical analysis revealed positive for murine double minute 2 (MDM 2) and cyclin dependent kinase 4 (CDK 4). Therefore, this sarcoma was diagnosed to be dedifferentiated liposarcoma. Since the surgical margin was positive, an additional wide resection including the surrounding normal tissue was performed. Complete excision was achieved after re-resection. He was alive 12 months postoperatively without any signs of recurrence. Dedifferentiated liposarcoma of the spermatic cord is a rare neoplasm. To the best of our knowledge, the present case is the 14th reported case in Japan. |
