Giant retroperitoneal liposarcoma presenting as indirect inguinal hernia.

Abstract

The rare case of giant retroperitoneal liposarcoma with scrotal sac extension was herein reported in a 56 year-old man. The initial symptoms began with abdominal distension subsequently left inguinal and scrotum enlargement. The ultrasonography demonstrated diffuse echogenic abdomen and nearly entire fluid-filled bowel loops were displaced into upper abdomen. The computed tomography revealed a huge fat attenuation tumor occupied in the retroperitoneum and extended to left sided pelvic cavity, left inguinal region and left scrotum.Intraoperative found rather well defined tumor within retroperitoneal space that extended
through the left inguinal canal into left scrotum. The tumor weighing 11 kg was excised. Left herniorrhaphy and left orchidectomy were also performed. Histopathological diagnosis showed liposarcoma of the retroperitoneum; well-differentiated subtype. The patient has received neither radiation nor chemotherapy after surgery.
