Retroperitoneal Liposarcoma with Metastasis to both Orbits: an Unusual Metastatic Site

Abstract

Liposarcoma is among the most common adult histotypes of soft tissue sarcoma. It usually arises from the deep soft tissue of the extremities or the retroperitoneum. Despite the high content of fat in the orbit, both benign and malignant tumors of adipose tissue are extremely rare at this site; reports describing liposarcoma metastatic to the orbit are rare. Our report is a new case and the appropriate methods for diagnosis and treatment of this unusual metastatic site in this type of cancer are discussed.
