Laparoscopic-assisted surgery for liposarcoma of the spermatic cord extending to the retroperitoneal cavity through the internal inguinal ring.

INTRODUCTION: Liposarcoma of the spermatic cord is a rare disease, reportedly treated with radical high orchiectomy. However, laparoscopic-assisted surgery for spermatic cord liposarcoma extending to the retroperitoneal cavity through the internal inguinal ring has not yet been reported. CASE PRESENTATION: A 78-year-old man had a spermatic cord tumor that extended to the retroperitoneal cavity through the internal inguinal ring and invaded the abdominal wall muscles. We performed laparoscopic-assisted surgery and successfully separated the tumor from the contiguous organs and vessels. The tumor was resected en bloc with abdominal wall muscles, and a muscular defect was repaired with a left tensor fascia lata muscle flap. Pathological analysis revealed a well-differentiated liposarcoma with negative surgical margins. There was no recurrence at 1 year post-surgery. CONCLUSION: Laparoscopic-assisted surgery is a feasible and minimally invasive procedure for treating liposarcoma of the spermatic cord extending to the retroperitoneal cavity through the internal inguinal ring.
