Abstract

Liposarcoma is the most common tumor type of retroperitoneal soft tissue sarcomas. Liposarcoma is a malignant tumor of mesenchymal origin in which the bulk of tumor differentiates into adipose tissue. A 50 year old male patient was presented at our clinic with abdominal mass and pain. Abdominal ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) showed a huge retroperitoneal mass. Hematologic, biochemistry and tumor markers were normal. Then, he was operated. He was reported as case well-differentiated retroperitoneal liposarcoma that weighted 3.000g.

Key words: Liposarcoma, retroperitoneal mass, sarcoma.
