Book excerpt: This book focuses on clinical presentation, diagnostic processes and current management of systematic vasculitis, and for this second edition the Editors have updated the treatment approach and nomenclature in line with current practice. Systemic vasculitides are a group of disorders which are of increasing importance. Many of these conditions are only rarely encountered by general physicians and often present significant diagnostic challenges. The Editors aim to provide easily accessible information in a pocket sized format. In doing so they hope to help both the generalist but also rheumatologists who only encounter these problems occasionally.
