Synovial chondromatosis is an uncommon disorder characterized by cartilaginous proliferation in the synovium. The cartilaginous nodules occur in the synovial membrane of a joint, bursa, or tendon sheath. It frequents large joints including knee, hip, and elbow. Synovial chondromatosis originating from the first metatarsal is extremely rare. We report a case of 37-year-old man with synovial chondromatosis of the first metatarsal.

Although synovial chondromatosis is most frequently found in the knee, they have been reported in temporomandibular joint. Synovial chondromatosis is a cartilaginous metaplasia of the mesenchymal remnants of the synovial tissue of the joint. It is characterized by the formation of cartilaginous nodules (loose bodies) in the synovium and within the articular space. Pain and swelling are the most common symptoms of the synovial chondromatosis and somtimes deviation of the mandible toward the unafected side during motion may occur. When these lesions becom symptomatic, they should be removed surgically.

Synovial chondromatosis is the chondroid metaplasia of the synovial membrane, Large joints such as the knee and hip are commonly involved. Synovial chondromatosis very rarely develops within the shoulder joints. We have experienced the synovial chondromatosis developed in the right subscapular recess communicating the shoulder joint of a 30 year-old-female who was diagnosed by plain radiograph, MRI and microscopic findings, and then treated by arthroscopic synovectomy and removal of loose bodies.

Synovial chondromatosis is a rare benign lesion originating from the synovial membrane. It presents as adhesive or non-adhesive intra-articular cartilaginous loose bodies. Although the causes of synovial chondromatosis have not been fully elucidated, inflammation, external injury, or excessive use of joints have been suggested as possible causes. Synovial chondromatosis has been reported to occur most frequently at large joints that bear weights, with a rare occurrence at the temporomandibular joint (TMJ). When synovial chondromatosis develops at TMJ, clinical symptoms, including pain, joint sounds, and mouth opening may common. Moreover, synovial chondromatosis rarely spreads to the mandibular condyle, glenoid cavity, or articular eminence of TMJ. The goal of this study was to discuss the methods of surgery and other possible considerations by reviewing cases of patients who underwent surgery for synovial chondromatosis that extended to the temporal bone.

Synovial chondromatosis is a rare, benign, monoarticular arthropathy that is characterized by the development of highly cellular, metaplastic cartilaginous nodules in the synovial membrane. It commonly affects larger joints such as the knee, elbow, wrist, shoulder, and hip. Synovial chondromatosis of the temporomandibular joint(TMJ) is rare. Moreover, the temporal involvement of synovial chondromatosis without connection with joint is greatly rare. A 44-year-old women had experienced pain of the right TMJ area and limitation of mouth opening. MRI and CT revealed multiple calcified loose bodies and widening in right upper joint space of TMJ and osteolytic lesion in right temporal bone. Treatment consisted of removal of multiple loose bodies, resection of the osteolytic lesion through the preauricular approach. She was diagnosed with primary transitional synovial chondromatosis of TMJ with involvement of temporal bone. In spite of remaining of the loose bodies, pain and mouth opening improved and there have been no recurrence of signs and symptoms for 5 years follow up.

Synovial chondromatosis is a rare disease. The knee is the most commonly affected joint but the shoulder joint is very rarely affected. We report typical synovial chondromatosis of the shoulder joint which was managed by arthroscopic removal of multiple loose bodies, synovectomy, good objective and functional outcome was obtained until postoperative 7-year follow-up. Arthroscopy can be used as an effective and useful therapeutic method for synovial chondromatosis of the shoulder joint.

Synovial chondromatosis is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue, usually intraarticular, commonly affects the knee, hip and elbow. An extraarticular lesion is rare, most often seen in a synovial sheath and bursa of the hand or foot. We present a case of extraarticular synovial chondromatosis in the left ankle, originated from the FHL tendon sheath of a 31 year-old-female diagnosed by a radiography, MRI confirmed histopathologically.

Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is a relatively common benign tumor of the skeleton, occurring most often in the metaphyseal region of long bone. However, it is rare in the facial bones. Reported foci in the mandible were the condyle, coronoid process, and symphysis region. Synovial chondromatosis is an uncommon benign condition of unknown etiology which affects the articular joints. Foci of cartilage develop through metaplasia in the underlying connective tissue of the synovial membrane. These cartilagenous foci and fragments may undergo calcification and ossification. We experienced 4 patients with abnormal appearance of mandibular condyle. This report describes 3 cases of osteocondroma and 1 case of synovial chondromatosis of the mandibular condyle with review of the literature.

Background Synocial chondromatosis(SC), a proliferative disorder of the synovial membrane. The etiology or cause of SC remains unclear. SC usually occurs in large articular joints such as knee, hip, elbow, and ankle. SC of the TMJ is very rare. It is a benign disease that mainly affects unilateral side. It can form cartilagenous and calcified loose bodies of various sizes and cause abnormal function of TMJ. Case Report In this paper, we report two cases of SC in the upper joint space of the left TMJ. One complained that "Sometimes the left jaw joint feels disoriented" and the other had no symptoms. CT scan and MRI showed left TMJ space widening, multiple tiny calcified mass. After clinical and radiographic analysis, we performed surgical removal of the lesion under genereal anesthesia. In the histologic examination, synovial chondromatosis was diagnosed in both patients. Conclusions We report two cases of synovial chondromatosis in the upper joint space of the left TMJ. We performed surgical removal of the lesion. The two patients showed good prognosis without recurrence or pain up to date.

In benign exophytic lesion in TMJ such as osteoma, chondroma, osteochondroma, synovial chondromatosis etc, symptom such as pain, mouth opening limitation, Most case of condylar exophytic lesion manifest with facial asymmetry, malocclusion, mandibular midline deviation. An osteochondroma and synovial chondromatosis are most commom benign condylar tumor. However this tumor is most frequently found on long bone and flat bone and is unusual on the skull. We report cases of osteochondroma, synovial chondromatosis of TMJ and review literatures.
