Diffuse pigmented villonodular tenosynovitis of the ulnar bursa--a case report

Area of Science:

• Orthopedics
• Pathology

Background:

• Pigmented villonodular tenosynovitis (PVNS) is a rare, benign neoplastic proliferation of the synovium.
• The localized nodular form is more common in the hand than the diffuse type.

Observation:

• This case report details a rare instance of diffuse PVNS affecting the entire ulnar bursa in the hand.
• The diffuse form presents distinct challenges compared to the more frequently encountered localized nodular PVNS.

Findings:

• The diffuse form of PVNS involving the hand is infrequently reported in medical literature.
• Complete tenosynovectomy is the recommended treatment for diffuse PVNS of the ulnar bursa.

Implications:

• Accurate diagnosis and surgical management are crucial for diffuse PVNS of the hand.
• Further research into the pathogenesis and optimal treatment strategies for diffuse PVNS is warranted.
