“…Extra-articular tenosynovial chondromatosis in the hand has been reported to commonly affect adults in the fifth decade of life [6]. The mean age of patients at the time of surgery was 59.0 ± 11.3 years.…”

“…Some nodules may have bony trabeculae with bone marrow, and be referred to as osteochondromatosis, as seen in case 1 in this report. The differential diagnoses of extra-articular tenosynovial chondromatosis include cartilage forming benign tumors of a soft-tissue chondroma and a periosteal chondroma [6]. A cartilage-forming benign tumor is known for its lack of synovial lining.…”

“…Articular synovial chondromatosis typically involves large joints such as the knee and the hip [4, 5]. Extra-articular tenosynovial chondromatosis is considered to be an anatomical counterpart of articular synovial chondromatosis, and tends to occur in the hands and feet [6-8]. …”

Background:Synovial chondromatosis is characterized by cartilaginous metaplasia in synovial tissues. Extra-articular tenosynovial chondromatosis is considered to be an anatomical counterpart of articular synovial chondromatosis. Extra-articular tenosynovial chondromatosis occurs preferentially in the hand, although its frequency is low.Results:We report three cases of extra-articular tenosynovial chondromatosis. A 65-year-old female presented with a history of symptoms over 40 years related to the dorsum of her index finger (Case 1), A 46-year-old female presented with a 6-month history of symptoms at the volar surface of her middle finger (Case 2), and a 66-year-old male presented with a 3-month history of symptoms in a dorsal ring finger. Case 2 had evidence of ossification, which could be classified as osteochondromatosis. Interestingly, the index finger lesions (Case 1) were accompanied by excessive bone involvement. The signal intensity of T2-weighted magnetic resonance imaging varies from low to high, possibly reflecting histological variations, such as ossification and fatty tissue changes. All lesions were resected without complications.Conclusion:Variations in anatomical sites suggest that overuse or mechanical overloading was not causative. Extensive involvement of the nearby tendon and joint capsule, as well as the bone, would require attention during the resection. Preoperative analysis of images is important, not only for the diagnosis, but also to assess the extent of the lesion, particularly given the complex anatomy of the finger.

Tenosynovial chondromatosis (TC) is a rare progressive benign tumor from the synovial lining of tendon sheath. The TC mostly affects males between the ages 30 to 50 years old at the ventral side of wrist. There are two different forms of TC that have been proposed in previous studies: an idiopathic cause (primary TC) and a joint related diseases cause (secondary TC). Even though trauma has been written to be a common reason for TC, a case of a secondary TC affecting the dorsal wrist following a triquetrum fracture has never been written before. The aim of this report is to present a rare case of a solitary post-traumatic TC at the dorsal wrist following a triquetrum fracture. We describe the clinical presentation, imaging modalities, histopathological and treatment challenges to manage this difficult lesion.

Rationale:Carpal tunnel syndrome (CTS) is the most common peripheral nerve neuropathy resulting from compression of the median nerve as it traverses the carpal tunnel. The pathophysiology of this condition is multifactorial, and majority of cases of CTS are idiopathic. We report cases of CTS caused by synovial osteochondromatosis (SOC), which has rarely been reported.Patient concerns:A 45-year-old female was admitted to the clinic due to right hand tingling sensation for 4 months. On physical examination, the patient's symptoms and signs corresponded to the median nerve entrapment at wrist. However, there is mild swelling and tenderness around the second metacarpal bone. Pain was aggravated during wrist and finger flexion.Diagnoses:An electrodiagnostic study revealed CTS. She was advised to begin splinting the hand using a wrist brace and to undergo physiotherapy. After 2 weeks, the tingling sensation decreased slightly. However mild swelling and tenderness around the second metacarpal bone did not improve. Ultrasonography showed multiple echogenic foci. Magnetic resonance imaging (MRI) revealed a nodule at the proximal metacarpal level with synovial thickening, enhancement, and a calcified shadow close to the flexor tendon. After confirming the presence of an osseous nodule with synovial thickening, the patient underwent surgeryInterventions:Carpal tunnel release and mass excision with synovectomy of the adjacent structures were performed. Histologically, the lesion was compatible with a diagnosis of SOC.Outcome:The symptoms have improved.Lessons:CTS due to SOC on finger flexor tendon is rare but should be considered for possible etiology. Appropriate clinical examination, plain radiography, ultrasonography, and MRI will help physicians to diagnose this condition. In this paper, we report the successful diagnosis and treatment of CTS caused by SOC within the finger flexor tendon.
