Cutaneous vasculitis and other neutrophilic dermatoses

During 1991 and 1992 there was an abundance of articles dealing with vasculitis and its cutaneous manifestations, as well as with the perhaps related disorders known as neutrophilic dermatoses. This brief review will deal with some of the more controversial areas. The specific issues discussed are those relating to the "new" American College of Rheumatology classification system and its application to patients who have skin lesions of vasculitis, the recently associated diseases, and the newer therapies for vasculitis. In addition, recent publications regarding acute neutrophilic dermatosis (Sweet's syndrome) and pyoderma gangrenosum are briefly discussed.
