A Case Demonstrating the Diagnostic and Surgical Difficulties of a Primary Dedifferentiated Retroperitoneal Liposarcoma

Abstract

This case report describes the presentation and management of an extremely large, dedifferentiated primary retroperitoneal liposarcoma. We discuss the diagnostic and surgical challenges due to massive tumor size and dedifferentiated tissue characteristics. Radiologic and pathologic features are reviewed to promote awareness and understanding of Dedifferentiated Liposarcoma (DL).
