Synovial chondromatosis is a rare benign disease, the aetiology of which is not clear. It can arise in the synovial membrane of joints, tendon sheaths, or bursae. Synovial chondromatosis is characterized by multiple loose bodies that can grow and cause symptoms such as pain, swelling and a limited range of motion. Read More

A Multidisciplinary Approach to Synovial Chondromatosis of the Temporomandibular Joint With Cranial Base Involvement: A Brief Review of the Literature and Case Report.

J Oral Maxillofac Surg 2020 May 15. Epub 2020 May 15.

Professor, Departments of Pathology, Oral and Maxillofacial Surgery, and Radiology, University of Tennessee Medical Center, Knoxville, TN.

Synovial chondromatosis (SC) is an infrequent, benign condition of unknown etiology affecting the synovium within articular joints. Often considered a metaplastic process, multiple cartilaginous nodules develop in the confines of the synovial membrane. In time, these cartilage nodules develop into fragments, sometimes detaching from the synovium and, thus, become loose in an adjacent synovial cavity. Read More

Department of Orthopedic Surgery, Kindai University Hospital, Osaka-Sayama, Osaka 589-8511, Japan.

Synovial osteochondroma (SO) is a relatively uncommon tumor affecting the synovial joints that is characterized by the development of hyaline cartilage from the synovial membrane. The basic pathophysiology of SO is thought to be the metaplastic change of the synovium to hyaline cartilage. Large extra- or para-articular lesions in the Hoffa's fat pad are relatively uncommon.

Soft Tissue Special Issue: Chondroid Neoplasms of the Skull.

Head Neck Pathol 2020 Mar 16;14(1):83-96. Epub 2020 Jan 16.

Division of Anatomical Pathology, Department of Pathology and Laboratory Medicine, The Ottawa Hospital/University of Ottawa, 501 Smyth Rd, 4th Floor CCW, Room 4250, Ottawa, ON, K1H 8L6, Canada.

Clinically, radiologically, and pathologically, chondroid neoplasms of the skull can be diagnostically challenging due to overlapping features in each of these domains. Compounding the problem for the pathologist, there is also significant morphologic, immunophenotypic, and molecular genetic overlap between benign and malignant cartilaginous lesions, and the majority of these lesions are encountered quite rarely in routine surgical pathology practice. Each of these factors contribute to the diagnostic difficulty posed by these lesions, highlighting the importance of radiologic-pathologic correlation in the diagnosis. Read More

Department of Radiology, Thomas Jefferson University Hospital, 132 S. 10th Street, 10th Floor, Philadelphia, PA, 19107, USA.

Objective: A variety of benign and neoplastic lesions can affect the synovium, including pigmented villonodular synovitis (PVNS) and synovial chondromatosis. Prior to surgical resection, accurate characterization of synovial lesions is necessary for appropriate treatment planning. Additionally, recent advances in potential medical therapies for PVNS could decrease or eliminate the need for surgery in some cases. Read More

Electronic address:

Rationale: Fibrodysplasia ossificans progressiva (FOP) is primarily a disease of progressive heterotopic ossification (HO) leading to impaired mobility throughout life. An additional diagnostic feature is a characteristic malformation of the great toes. The culpable gene for FOP,ACVR1 (activin A receptor type 1) has a clear effect on the induction of extra-skeletal bone formation. Read More

Potential utility of anti-TNF drugs in synovial chondromatosis associated with ankylosing spondylitis.

Int J Rheum Dis 2019 Nov 24;22(11):2073-2079. Epub 2019 Oct 24.

Department of Rheumatology and Immunology, Peking University Shenzhen Hospital, Shenzhen, China.

We describe a previously unreported association of ankylosing spondylitis with synovial chondromatosis, and briefly review previously reported cases and treatment of synovial chondromatosis in patients with other immune-mediated inflammatory arthritides. A 20-year-old man with ankylosing spondylitis whose axial disease was in remission with nonsteroidal anti-inflammatory drugs and oral disease-modifying anti-rheumatic drugs developed recurrent right knee pain and swelling. Magnetic resonance imaging of his right knee revealed calcified loose bodies, suggestive of synovial chondromatosis. Read More

A molecular study of synovial chondromatosis.

Genes Chromosomes Cancer 2020 03 18;59(3):144-151. Epub 2019 Oct 18.

Department of Pathology, Memorial Sloan Kettering Cancer Center, New York, New York.

Synovial chondromatosis (SC) is a rare benign cartilaginous neoplasm in which recurrent fibronectin 1 (FN1) and activin receptor 2A (ACVR2A) gene rearrangements have been recently reported. Triggered by a case of malignant transformation in SC (synovial chondrosarcoma) showing a novel KMT2A-BCOR gene fusion by targeted RNA sequencing, we sought to evaluate the molecular abnormalities in a cohort of 27 SC cases using a combined methodology of fluorescence in situ hybridization (FISH) and/or targeted RNA sequencing. Results showed that FN1 and /or ACVR2A gene rearrangements were noted in 18 cases (67%), with an FN1-ACVR2A fusion being confirmed in 15 (56%) cases. Read More

Synovial chondromatosis is a rare condition characterized by benign chondrogenic meta- plasia of extra-articular synovial tissue. It usually affects a single tendon sheath of the hand or foot. This report describes a rare case with extensive synovial chondromatosis affecting all flexor tendons in the tarsal tunnel, its radiological features, surgical treatment, and clinical outcome.

Division of Orthopaedics, Addenbrooke's Hospital, Cambridge University Hospitals Trust, Cambridge, UK.

Osteochondritis dissecans (OCD) of the humeral head is rare and usually occurs in adolescents. Secondary synovial chondromatosis occasionally occurs in the shoulder but has only been reported twice in an adolescent. We describe the case and management of an adolescent male who presented with features of OCD and secondary chondromatosis in his shoulder occurring simultaneously. Read More
