Ultrasound as a tool for the early diagnosis of psoriatic arthritis

Psoriasis is a common chronic, immune-mediated, systemic inflammatory disease, with a special predilection for the skin and joints. Approximately one third of patients with psoriasis will have associated psoriatic arthritis and it usually begins with the skin lesions, evolving to articular manifestations. Since psoriatic arthritis could present with permanent articular damage with chronic pain and disability, it is important to seek for early diagnosis. We will talk about our recent experience with rheumatological ultrasound, studying a small and selected group of patients, along with an important literature review.
