Introduction

Abstract

The goal of this book is to present the current knowledge about a group of skin conditions collectively known as the Neutrophilic Dermatoses. It is rather unusual for dermatologists to name cutaneous diseases according to the main cellular type found in the lesions. In doing so, and not bringing to the foreground the clinical appearance of the lesions, one could expect a wide variety of clinical aspects. Indeed, some neutrophilic dermatoses are pustular, others are papular, nodular, ulcerative, and the diversity of their appearance gave rise to a great number of denominations when distinct clinical entities were described by twentieth century dermatologists.
