Arthritis mutilans is a rare form of psoriatic arthritis, being found in only 1%-5% of patients. Spondylitis with or without sacroiliitis occurs in approximately 5% of patients with psoriatic arthritis and has a male predominance. Although its incidence is probably underestimated, SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis) is a rare condition. Asymmetrical oligoarticular arthritis accounts for nearly 70% of all cases of psoriatic arthritis.
