Pigmented villonodular synovitis (PVNS) is a benign joint disease best characterized on magnetic resonance imaging (MRI). The role of fluorine 18 fluorodeoxyglucose ((18)F-FDG) position emission tomography-computed tomography (PET-CT) in the diagnosis or characterization remains unclear. PVNS displays as a focal FDG avid lesion, which can masquerade as a metastatic lesion, on PET-CET. We present a case of PVNS found on surveillance imaging of a lymphoma patient.

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.

Emerging therapeutics in the management of tenosynovial giant cell tumor (TGCT).

Expert Rev Anticancer Ther

December 2024

Department of Internal Medicine, Division of Hematology/Oncology, University of Michigan, Ann Arbor, MI, USA.

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.

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.

Soft tissue mass resembling myxochondroid metaplasia in Achilles tendon.

Skeletal Radiol

December 2024

Department of Radiology, University of Pittsburgh, UPMC Montefiore, 200 Lothrop Street, Pittsburgh, PA, NE 538.3, 15213, USA.

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.

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.
