Summary: This study aims to establish a favorable preclinical translational platform for validating efficient and personalized therapeutic candidates for TGCT. The use of patient-derived tumor xenograft (PDTX) mouse models in nude mice and ex vivo cultures of patient-derived explants (PDEs) were shown to be effective in evaluating response patterns to CSF1R inhibitors.

Summary: This study reports a rare case of pigmented villonodular synovitis (PVNS) causing knee popping symptoms. MRI sequences revealed that the lesion moved forward through the interstice between the PCL and the ACL at 120 degrees of knee flexion, explaining the popping.

Summary: Pigmented villonodular synovitis (PVNS) is a rare and relatively benign intra-articular lesion characterized by the slow growth of synovial tissue. It is most commonly found in the knee joint and can be localized or diffuse based on synovial involvement. Arthroscopic and excisional resections are recommended as treatment methods, and radiotherapy or chemotherapy can be used as adjuvant therapies for widespread masses. This study presents a case of diffuse PVNS originating from the patellar fat pad.

Summary: This study evaluated the long-term functional outcomes and disease control among treatment modalities for diffuse pigmented villonodular synovitis of knee. It found that adding moderate-dose adjuvant radiotherapy following synovectomy provided excellent local control and maintained good joint function with limited treatment-related morbidity.

Summary: This study retrospectively reviewed patients who underwent hip arthroscopic procedures for PVNS by the senior author from 2012 to 2016. The results showed favorable short to mid-term outcomes with arthroscopic subtotal synovectomy in patients with hip PVNS and no advanced osteochondral damage at presentation, with no recurrence based on follow-up MRI.

Summary: Diffuse TGCTs of the foot and ankle region have a significant recurrence rate irrespective of therapeutic procedures, while lTGCTs are well treatable lesions with low recurrence and moderate complication rates. Larger prospective multi-center studies are needed to confirm these results and recommendations.

Summary: This study retrospectively analyzed the clinical characteristics, surgical treatment, and prognosis of patients with D-TGCT involving the TMJ and the skull base. The results showed a recurrence rate of 4.5% after complete resection, and tumor recurrence rates of 9.1% and 15.8% for surgery alone and postoperative radiotherapy, respectively. Overall, D-TGCT involving the TMJ and the skull base is locally aggressive but has a good prognosis.

Summary: This study found that the risk of local recurrence in tenosynovial giant cell tumor is correlated with the type and location of the lesion, with the diffuse type and knee location as independent risk factors. The risk factors for osteochondral destruction are mainly related to the type of lesion, while local recurrence and osteochondral destruction are somewhat associated.

Summary: PVNS is a rare disease with hyperplasia of the synovium, and this study explores the relationship between cIAP2 expression and various factors in the disease. Higher cIAP2 expression in DPVNS synovium was associated with proliferation, anti-apoptosis, and invasive growth, potentially leading to recurrence and poor prognosis.

Summary: Primary pachydermoperiostosis is a rare genetic disease that affects the skin and musculoskeletal system. It is considered a benign condition unlike secondary hypertrophic osteoarthropathy. While various associated abnormalities have been described, no previous literature has reported an association with tumors. This case presents the first instance of a 20-year-old man with primary pachydermoperiostosis revealed by a knee synovial tumor.

Summary: In order to reduce the recurrence rate of PVNS, the author pioneered the arthroscopic total synovial peel (ATSP). The results of the study showed that this method significantly reduces the postoperative recurrence rate of diffuse PVNS, indicating that it may be a viable option for treating PVNS via arthroscopy.

Summary: This report presents a unique case of localized pigmented villonodular synovitis of the knee in a misdiagnosed patient with intra- and extraarticular lesion, likely related to knee trauma history and a focal defect in the lateral patellar retinaculum. Open synovectomy effectively relieved symptoms of limited mobility and pain with no recurrence observed up to 18 months postoperatively.

Summary: Tenosynovial giant cell tumour (TGCT) is a rare, locally aggressive tumor that arises from the joints, bursa, and tendon sheaths. There are two types of TGCT: nodular and diffuse, with the former exhibiting a slow disease course and the latter showing locally aggressive behavior. Although not life-threatening, TGCT can cause chronic pain and negatively impact function and quality of life. CSFR1 inhibitors are effective in treating TGCT but are not widely available. The lack of guidelines and uncertainty in selecting appropriate therapy lead to inconsistent adoption of new treatments and suboptimal outcomes for patients. A global consensus meeting was held in June 2022 to develop evidence-based recommendations for the optimal management of TGCT.
