PsA is accompanied by both peripheral and axial manifestations of musculoskeletal disease. Peripheral joint diseases include polyarticular, oligoarticular, distal, and arthritis mutilans subtypes. Asymmetrical oligoarticular arthritis with or without spine involvement is one of the most common subtypes of PsA, particularly in the early disease state; many patients progress to more symmetrical polyarticular disease.

About 25% of patients with PsA may have axial disease (axPsA). Most patients with axPsA have peripheral arthritis but only 2%-5% will have exclusive axial disease. Although its incidence is probably underestimated, SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis) is a rare condition that can sometimes be associated with pustular psoriasis. Arthritis mutilans is a rare form of PsA.
