Joint Affections in Systemic Diseases
Bourdillon  described in 1888 the coincidence of psoriasis and arthritis and postulated an etiological relationship between them. This connection was subsequently discounted by Gribble  and Margolis  who interpreted the arthritis in their cases as rheumatoid arthritis occurring incidentally in psoriasis. Coste  also considered the joint affection in psoriasis as rheumatoid arthritis but with its features modified by a psoriatic background. However, distinct differences in certain clinical traits and laboratory findings led Bennett , Dawson et al. , DeSeze et al. , Moll et al. , and Wright  to consider the joint changes occurring in psoriasis as a disease of its own, and basically related to psoriasis.
