Laparoscopic Resection of a Dumbbell-type Spermatic Cord Liposarcoma

Abstract

A 51-year-old man was diagnosed with a left inguinal hernia and underwent laparoscopic surgery at another hospital. However, intraoperatively, no hernia sac was identified, and prolapse of fatty tissue was observed at the internal inguinal ring. He presented to our hospital for further evaluation. Physical examination revealed a soft, left lower abdominal mass that was 10 cm in size. Computed tomography revealed a large dumbbell-shaped, predominantly fat-containing mass (17 cm), extending from the abdominal wall to the peritoneal cavity through the internal inguinal ring. We diagnosed the patient with a liposarcoma of the spermatic cord and performed laparoscopic-assisted tumor excision with orchiectomy. Histopathological findings confirmed the diagnosis of a well-differentiated liposarcoma. Spermatic cord liposarcomas are rare, and dumbbell-shaped tumors are extremely rare. Laparoscopic resection of liposarcomas is reported in the recent literature. We performed successful laparoscopic R0 resection of the rear peritoneal side through a minimal wound. The combination of laparoscopy is useful for liposarcoma in consideration of the localization of tumors.
