Neoplasms of the joint

Abstract

Although some neoplasms originate in the joint, others penetrate or metastasize to it. Pigmented villonodular synovitis and synovial chondromatosis are the most common proliferative disorders arising from within the joint. Other primary lesions are rare and include lipoma arborescens, synovial hemangiomas, intracapsular chondromas, and synovial chondrosarcomas. Synovial sarcoma and giant cell tumors are neoplasms that tend to extend into the joint. The malignancies that metastasize to bone also may invade the articular space. © 2008 Springer-Verlag New York.
