Typically EXOS affect the older patient, usually presenting in the sixth decade of life, in contrast to their skeletal counterparts that normally present in the first three decades of life. 1_3 Males are predominantly affected with a male to female ratio of 1.9: 1.1 The lower extremity is the most common location (50 to 68%) followed by the upper extremity (1 1.5%) and the retroperitoneum (1 1.5 to 17%). Preoperative evaluation in patients with retroperitoneal sarcomas should include a thorough history and physical examination with special focus on symptoms and signs of lymphoma, germ cell tumors, and adrenal tumors.
