Pigmented villonodular synovitis in a child

Area of Science:

• Orthopedics
• Pathology
• Radiology

Background:

• Pigmented villonodular synovitis (PVNS) is a rare joint disorder.
• It typically affects larger joints like the knee or hip.
• PVNS is uncommon in pediatric populations and the ankle joint.

Observation:

• A case of PVNS in an adolescent patient is presented.
• The patient exhibited monarticular involvement exclusively in the ankle.
• No congenital anomalies or family history of the condition were noted.

Findings:

• The case highlights the atypical presentation of PVNS in the ankle of a young patient.
• Clinical, radiological, and pathological features of this specific PVNS case are reviewed.
• The rarity of PVNS in the ankle and in childhood is emphasized.

Implications:

• This case expands the understanding of PVNS presentation in adolescents.
• It underscores the importance of considering PVNS in pediatric ankle effusions.
• Further research into pediatric PVNS is warranted for improved diagnosis and management.
