The rheumatology/dermatology collaboration.

Psoriatic arthritis (PsA) of often has a destructive course, characterized by progressive damage to bone and joints. Consequently, prompt detection is critical, allowing effective, disease-modifying treatment to be administered at the earliest possible point in the progression of the disease. The collaboration between dermatologic and rheumatologic professionals in the early diagnosis, and subsequent management, of PsA is explored, with a focus on case studies that illustrate the potentialfor such collaboration.
