The cutaneous neutrophilic vascular injury syndromes: a review.
The skin manifestations of vasculitis reflect injury by all of the classic immune reactions of Gell and Coombs. As the skin affords a window of opportunity for the clinician to obtain tissue for diagnostic purposes in patients with systemic vasculitic syndromes, a thorough understanding of the dermatopathologic manifestations of those systemic diseases is a considerable asset to the practicing pathologist. This review focuses on those systemic diseases that can provoke a small vessel neutrophilic injury pattern in the skin and provides clues by which these diseases can be separated from each other and from their innocuous mimics in which cutaneous vascular injury is the only significant consequence.
