Highly malignant tumor occurring in adolescents and young adults ages 10-25
Can develop in almost any bone or soft tissue but most common in pelvis, axial skeleton, and femur
Overt metastatic disease present in less than 25% at time of diagnosis but assumed present due to 80-90% relapse rate if treated locally
Typically present with pain or swelling of a few weeks or months of duration
Aggravated by exercise and worse at night Fever, fatigue, weight loss, or anemia are
present in 10-20% of casesClark, et all. NEJM, 2005
