Synovial sarcoma associated with osteofibrous dysplasia : a case report and review of the literature

We report on a 14-year-old boy who demonstrated an unusual association between osteofibrous dysplasia and synovial sarcoma. This case suggests that a patient who presents with osteofibrous dysplasia of the tibia can eventually develop a malignant musculoskeletal tumor in the same anatomical location (same limb). This experience suggests that a patient who presents with osteofibrous dysplasia should be followed up for the possibility of a coexisting synovial sarcoma in the same leg.
