Diffuse pigmented villonodular synovitis of the shoulder: a case report
1Department of Orthopedic Surgery, Taichung Veterans General Hospital, Taiwan, R.O.C.
Summary
Pigmented villonodular synovitis (PVNS) is a rare joint disorder affecting the shoulder. This study presents a unique case of shoulder PVNS with a rotator cuff tear, contributing to limited literature on this condition.
Area of Science:
- Orthopedics
- Rheumatology
- Pathology
Background:
- Pigmented villonodular synovitis (PVNS) is a rare, benign neoplastic proliferation of the synovium.
- It is characterized by synovial thickening, hemosiderin deposition, and inflammation.
- While commonly affecting the knee, PVNS can occur in other joints, including the shoulder.
Observation:
- Shoulder involvement in PVNS is exceptionally rare, with only 12 cases previously reported in English literature.
- This report details a specific case of PVNS in the shoulder joint.
- The case also presented with a simultaneous rotator cuff tear, a co-occurrence not previously documented.
Findings:
- The study presents a case of pigmented villonodular synovitis (PVNS) of the shoulder.
- This case is notable for its simultaneous occurrence with a rotator cuff tear.
- A review of existing literature on shoulder PVNS is included.
Implications:
- This case expands the understanding of PVNS presentation in the shoulder.
- It highlights the potential for co-existing rotator cuff pathology in shoulder PVNS.
- Further research is needed to elucidate the etiology and optimal management of shoulder PVNS.
