Summary
Pigmented villonodular synovitis (PVNS) is a rare knee disorder. Aggressive surgical resection via open arthrotomy is recommended for diffuse PVNS to prevent disease progression.
Area of Science:
- Orthopedics
- Oncology
- Radiology
Background:
- Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder of the synovial membrane, predominantly affecting the knee.
- The exact etiopathology of PVNS remains unclear.
- Current classification distinguishes between localized (LPVNS) and diffuse (DPVNS) forms, with MRI being the preferred diagnostic imaging modality.
Observation:
- This report details a rare case of diffuse PVNS in the right knee.
- The condition presented as a locally aggressive, destructive lesion with extensive invasion of the femur, tibia, fibula, and surrounding musculature.
- Magnetic Resonance Imaging (MRI) is crucial for diagnosis.
Findings:
- The diffuse form (DPVNS) presents treatment challenges, with ongoing debate regarding arthroscopic versus open arthrotomy for synovectomy.
- A radical synovectomy via open arthrotomy was performed in this case.
- Tumor prosthesis implantation was utilized to halt disease progression.
Implications:
- Complete and aggressive resection of affected tissue through open arthrotomy is recommended for managing locally aggressive PVNS.
- This approach, combined with appropriate diagnosis, is crucial for preventing disease advancement.
- Further research into PVNS etiopathology and optimal treatment strategies is warranted.
