摘要

Cutaneous disease is a central component of psoriatic arthritis (PsA), contributing substantially to patient disease burden and influencing therapeutic choices. Beyond plaque psoriasis, specific phenotypes, including nail, scalp, palmoplantar, and inverse involvement, are relatively common in PsA and are frequently associated with greater functional limitation, impaired quality of life, and discordant responses to systemic therapy. Accurate identification of these manifestations is critical for diagnosis, risk stratification, and treatment optimization. This review provides a clinically oriented overview of the dermatologic spectrum of PsA, outlining epidemiology, pathogenic mechanisms linking the skin–joint axis, and the impact of skin disease on outcomes. We summarize evidence for topical therapies, conventional systemic agents, biologics targeting tumour necrosis factor alpha (TNFα), interleukin-17 (IL-17), and interleukin-23 (IL-23), targeted synthetic disease-modifying anti-rheumatic drugs (DMARDs), and emerging treatments, with attention to phenotype-specific considerations and multidisciplinary management. The implications of persistent skin activity in complex-to-manage PsA are also discussed. A domain-based, integrated approach to skin and joint care is required to achieve effective control both of musculoskeletal and cutaneous symptoms. Systematic evaluation and treatment of skin involvement should be considered a core component of PsA management rather than an ancillary concern.
