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.
