title: New insights into the concept of psoriatic disease.
abstract: The concept of psoriatic disease (PsD) derives from that of psoriatic arthritis (PsA), from which it evolved. The first step in this process was the concept of PsA; the second was the description of the wide clinical spectrum of PsA; and the third was the introduction of the new concept of PsD. This article describes this conceptual evolution and discusses emerging pathological implications deriving from it.
