Dear Editor, Synovial chondromatosis is a benign disorder of the synovial lining, characterized by the presence of loose cartilaginous bodies. Ossification of these cartilaginous bodies is known as osteochondromatosis. Although often benign, malignant transformation can occur. It typically presents unilaterally in large joints. The knee is the most commonly involved joint but it can also involve the shoulder, elbow, hip, ankle and temporomandibular joints. Synovial chondromatosis in patients with rheumatoid arthritis (RA) are reported. To the best of our knowledge, multiple-joint synovial chondromatosis with RA has not been reported in the literature thus far. Here we present a 48-year-old man, a case of seropositive RA with secondary synovial chondromatosis involving multiple joints.
