Case in brief
A 65-year-old female with a history of psoriasis presented with inflammatory hand pain and exhibited swan neck and Boutonniere deformities, along with tenderness in the distal interphalangeal joints and hallux varum. Active psoriatic plaques were noted over the interphalangeal joints. This case highlights the need for careful differentiation between psoriatic arthritis and rheumatoid arthritis due to differing treatment approaches.
Diagnostic / clinical pearl
Clinicians should be aware that psoriatic arthritis can present with hand deformities typically associated with rheumatoid arthritis, which may lead to misdiagnosis.
