Extra-articular tenosynovial chondromatosis of the right fifth digit in a 59-year-old man: A case report and literature review.

Tenosynovial chondromatosis is a rare benign disorder characterized by formation of cartilaginous bodies within the synovia of the tendon sheaths. Most commonly present in the hands and feet. Clinical presentation and plain radiography can be inconclusive, which can lead to misclassification, most often confused as a chondroma of soft parts. In this case, we report the clinical, radiologic, and histology of a 59-year-old man who presented with a 1-year history of mass on the right fifth digit with limitation of motion secondary to this condition. Surgical excision revealed multiple cartilaginous nodules of varying size arising from the flexor tendon sheath. The diagnosis was confirmed postoperatively by surgical histopathology. The postoperative course of the patient was uncomplicated and has achieved an excellent functional recovery.

Post-traumatic tenosynovial chondromatosis following a triquetrum fracture: a case report

ABSTRACT 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.

Extra-Articular Tenosynovial Chondromatosis of the Finger: A Case Series Study of Three Cases, One Including Excessive Osseous Invasion

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.

Extra-articular chondromatosis of flexor and extensor compartments of the hand: Case report and review of literature

Objectives: Tenosynovial chondromatosis is an uncommon type of chondro-dysplasia of synovial and connective tissue. We report a case of a patient with a primary right wrist extra-articular chondromatosis extending to the flexor and the extensor compartments. Methods: Until now, there has been no study describing double surgical access for such a case. Results: Due to the extension, two surgical accesses are required to completely remove the neoformation. Conclusions: At 2 years of follow-up, the good functional-clinical results and absence of recurrence confirm the validity of our surgical strategy.
