Psoriatic Arthropathy

Key points

• Psoriatic arthropathy correlates poorly with cutaneous psoriasis and often precedes the development of skin lesions.
• rheumatoid-like polyarthritis: (30-40%, most common type)
• asymmetrical oligoarthritis: typically affects hands and feet (20-30%)
• DIP joint disease (10%)
• arthritis mutilans (severe deformity fingers/hand, 'telescoping fingers') Management
