Retroperitoneal Liposarcoma: Report of a Case
摘要
Liposarcoma is one of the most common adult soft tissue sarcomas, and comprises several subtypes ranging in behavior from non-metastasizing neoplasms to high-grade sarcomas with full metastatic potential. Due to its varied and diverse appearances, liposarcoma causes much concern among clinicians. We report a case of an 80-year-old man suffering from retroperitoneal liposarcoma with an initial presentation of abdominal distension, protruded umbilicus, and bilateral lower leg swelling. Abdominal sonographic examination showed a giant tumor with multiple cyst-like structures over his right lower abdomen. Subsequent abdominal computed tomography revealed a huge, abdominal, mixed cystic and solid mass. Later the patient received debulking and jejunum segmental resection. Pathologic examination confirmed that the tumor was retroperitoneal liposarcoma. We also review the classification, clinical presentation, prognosis, and management of liposarcoma.
