5 Preface A basic knowledge of dermatopathology is essential for the diagnosis of both inflammatory and neoplastic skin diseases. Our goal in writing this book is to provide a structured well-illustrated introduction to dermatopathology for beginners, not to replace any of the existing standard textbooks. Since the German version was published in the spring of 2007, many positive comments suggest that we may have come close to achieving this goal. Thus we are especially happy to now be able to offer an English version, designed to reach a new group of readers. We would like to thank Gertrud Volkert MD of Steinkopff Verlag for her support and advice in planning and producing both editions. Michael Hertl MD reviewed the information on the diagnosis of blistering diseases. We have limited ourselves to the most common and important diseases in order to make the initial study of dermatopathology as simple and painless as possible. Each disease is presented in a structured fashion, with clinical description, histologic features, special stains, differential diagnostic considerations and comments accompanied by two representative photomicrographs with all of the important diagnostic features labeled with pointers. We have tried to pick representative sections so that the book is useful for the age-old learning tradition of matching pictures to what one sees under the microscope. Especially in the case of inflammatory skin diseases, the clinicopathologic correlation is often the key to the diagnosis. We have tried to mention essential points in the comments section. Similarly, the differential diagnostic possibilities are considered for each individual disease, leading sometimes to repetition, but hopefully enhanced learning and less page turning. We do read the literature but have deliberately not cited any references. Both the Internet and standard dermatopathology textbooks can provide as much directed reading material as anyone could possibly want. Our true hope for this book is that it succeeds in transferring our fascination and love of dermatopathology to at least a few members of the upcoming generations in our specialty.
