Summary
Pigmented villonodular synovitis (PVNS) of the shoulder presents insidiously with stiffness. Early surgical excision or synovectomy is the optimal treatment for this rare joint condition.
Area of Science:
- Orthopedics
- Pathology
Background:
- Pigmented villonodular synovitis (PVNS) is a rare joint disorder.
- Shoulder PVNS lacks a characteristic clinical presentation, often presenting insidiously with discomfort and stiffness.
Observation:
- Shoulder PVNS can be incidentally discovered during unrelated surgeries.
- Cystic and degenerative changes are more frequent in shoulder PVNS compared to other joints like the knee.
Findings:
- Histologic findings of shoulder PVNS are consistent with those observed in other joints.
- Optimal treatment involves early marginal excision for localized PVNS and total synovectomy for diffuse PVNS.
Implications:
- Incidental PVNS findings should not alter planned reconstructive procedures.
- Arthroscopic treatment and radiation therapy for diffuse shoulder PVNS remain uninvestigated.
