Presentation
Histological examination revealed a chondrosarcoma, which on the basis of imaging findings we present as having arisen from the synovium. [ncbi.nlm.nih.gov]
There can be a wide spectrum in age of presentation from from 25-75 years of age. A slight male predilection may be present. It can either as a primary lesion (primary synovial chondrosarcoma) or secondary to synovial chondromatosis. [radiopaedia.org]

Joint Effusion
Joint effusions and synovial thickening are commonly seen. The synovial thickening is best seen on postcontrast T1 fat-suppressed images. [jaocr.org]

Suggestibility
On MR imaging, the lobulated contours of the soft tissue mass suggested synovial chondromatosis. Histological examination revealed a chondrosarcoma, which on the basis of imaging findings we present as having arisen from the synovium. [ncbi.nlm.nih.gov]
This would suggest that for every 800 chondrosarcomas diagnosed, 5 originated in synovial chondromatosis; that is, 0.6% of chondrosarcomas are linked to primary synovial chondromatosis. [hindawi.com]

Workup
Laboratory workup revealed a normal white blood cell count: 7000/mm (normal; 4500-10,000/mm), a normal C-reactive protein: 1.0 mg/L (normal; 0-4 mg/L), and mildly elevated erythrocyte sedimentation rate count: 22 mm/h (normal; 20 mm/h). [sjosm.org]
Treatment
The treatment must be a wide resection or an amputation. [ncbi.nlm.nih.gov]
Regarding treatment for SCH, only 14 patients underwent limb-salvage surgery. Amputations were performed in 40 patients (59.7%). Five patients refused hemipelvectomy and in 5 cases treatment was not reported. [atm.amegroups.com]
Treatment and prognosis It is a malignant lesions which can metastasize. [radiopaedia.org]
Make informed clinical choices for each patient, from diagnosis and treatment selection through post-treatment strategies and management of complications, with new evidence-based criteria throughout. [books.google.com]
Prognosis
Treatment and prognosis It is a malignant lesions which can metastasize. [radiopaedia.org]
CONCLUSIONS: We concluded that prognosis of SCH is worse than conventional one and we speculated this is due to the difficult site of the tumor (intraarticular), diagnostic delay and inappropriate previous treatments. [ncbi.nlm.nih.gov]
According to Campanacci et al. the prognosis of SCH is comparable to that of conventional CHS and depends on the histological grade of malignancy of the lesion (1). [atm.amegroups.com]
Etiology
No etiological factors can be indicated, even though in some cases there is a history of trauma. No familiar cases were reported. Surgery ended up with amputation in 59.7% of cases. Local recurrence rate was 28.3%. [atm.amegroups.com]
ETIOLOGY: The etiology of synovial chondromatosis is not known. Some suspect that it is due to synovial irritation. This may be from trauma or possibly from infection, but this is unclear. No organism has ever been cultured. [gait.aidi.udel.edu]
Introduction Also known as synovial chondro-metaplasia Rare condition of unclear etiology in which foci of cartilage develop in the synovial membrane of joints, bursae, or tendon sheaths as a result of metaplasia of the subsynovial connective tissue Nodules [orthopaedicsone.com]
The true etiology remains unknown, but the metaplastic theory is the most favored. [orthopedics.imedpub.com]
