Four cases of primary rhabdomyosarcoma of long bone were reported, all confirmed by operation and pathology. There were 3 male and 1 female. The femur was involved in 1 case and tibia in 3. Based on the radiologic manifestations the tumor could be divided into two different types: (1) Osteolytic form: Presenting as large area of osteolytic destruction without periosteal reaction; (2) Mixed form: In addition to patchy osteolytic destruction, calcification or dense tumor bone in the medullary cavity or soft tissue can be seen, often associated with periosteal reaction.
