Intra articular synovial sarcoma

Abstract

Synovial sarcoma is a soft tissue neoplasm with a characteristic biphasic pattern. Incidence in soft tissues is 5-10%. Intra articularly synovial sarcoma is extremely rare. Fewer than 5% of all synovial sarcomas arise within the joint space. We report a case of intra articular synovial sarcoma in a young male who presented as internal derangement of the knee.
