Objective: Pigmented villonodular synovitis occurring in the region of the temporomandibular joint is a rare disease, requiring a review of the treatment method, follow-up period.
Method: Refer to the past literature, along with a retrospective search.
Results: An excision, including the skull base bone, was performed in all cases; however, recurrence was found in one case on which fractional excision was performed. Past reports have also indicated that en bloc resection was considered desirable.
Conclusion: It is necessary to perform en bloc resection on patients with pigmented villonodular synovitis occurring in the region of the temporomandibular joint. Furthermore, due to reported cases of recurrence after a long period of time, follow-up observations of about 10 years are considered necessary.

Pigmented villonodular synovitis (PVNS) is rare in the shoulder, with few descriptions in the literature. We present the case of a 58-year-old female patient with no history of trauma. The patient reported pain for 2 months with no limb irradiation and presented lifting strength loss and progressive limitation of active and passive mobility.

Article Synopsis
- Tenosynovial giant cell tumors (TGCTs) are aggressive tumors often found in younger individuals, leading to long-term disability and typically managed via surgery, which has its own risks.
- This review focuses on systemic treatment options, particularly for the diffuse subtype (DT-TGCT), and assesses recent advancements and the historical context of these therapies.
- Notable progress includes the development of CSF1 receptor-targeting therapies like pexidartinib, paving the way for further research on treatment effectiveness and optimizing patient outcomes.
Co-occurrence of Pigmented Villonodular Synovitis and Patellar Clunk Syndrome Following Total Knee Arthroplasty: A Case Report.

Orthopaedic Surgery, The University of Alabama at Birmingham, Birmingham, USA.
Pigmented villonodular synovitis (PVNS) is an uncommon hyperproliferative disease of the synovium presenting either as localized or a more aggressive diffuse form. Its occurrence following total knee arthroplasty (TKA) is rare, and its presentation alongside patellar clunk syndrome (PCS) has not been previously reported. We present a case of a 64-year-old female patient diagnosed with diffuse PVNS (D-PVNS) two and half years following TKA, co-occurring with PCS.

The Achilles tendon is the strongest and largest tendon in the human body, composed of the distal confluence of the gastrocnemius and soleus muscles and may also include the plantaris longus tendons. Despite its tremendous strength, it is frequently injured. Soft tissue tumors or tumor-like conditions of Achilles tendon are much less common in comparison to traumatic and infectious/inflammatory lesions.

J Knee Surg

Department of Orthopaedics, University of Maryland School of Medicine, Baltimore, Maryland.
Pigmented villonodular synovitis (PVNS) is a rare neoplastic proliferation of large joints, including the knee, with both localized PVNS (LPVNS) and diffuse PVNS (DPVNS) types. DPVNS is known to recur at a higher rate following resection; however, there is little evidence comparing patient-reported outcomes (PROs) between the two types. The purpose of this study was to compare PROs between patients with LPVNS and DPVNS involving the knee 2 years after surgical resection.
