Understanding Enthesitis in Psoriatic Disease: Insights and Implications.

Enthesitis represents a hallmark feature and central pathological process in psoriatic arthritis and has been proposed as a potential early indicator in patients with psoriasis prior to the onset of clinically apparent psoriatic arthritis. Given the risks associated with delayed diagnosis, there is growing interest in identifying at-risk patients early to enable timely interventions and personalized treatment approaches. In clinical practice, dermatologists are often the first to encounter these patients, highlighting the need for effective screening strategies in their setting. In recent years, efforts have been made to develop validated screening tools for the early detection of musculoskeletal symptoms in patients with psoriasis. Additionally, there has been a greater focus on improving assessments through imaging techniques such as ultrasound and magnetic resonance imaging. However, a universally accepted referral pathway has yet to be established, potentially creating gaps in care during the transition from psoriasis to psoriatic arthritis. This review synthesizes current evidence on the role of enthesitis in psoriatic disease, focusing on its underlying mechanisms, diagnostic approaches, and therapeutic strategies. Importantly, we propose a practical screening and referral pathway designed to support dermatologists in early recognition of at-risk patients, with the goal of facilitating timely rheumatology referral and multidisciplinary management. By emphasizing the complementary roles of questionnaires, clinical assessment, and targeted imaging, our approach aims to bridge existing gaps in care and optimize patient outcomes.
