An Atlas of Hair Pathology with Clinical Correlations PDF

Preface

This second edition differs from the first in several ways. There are now three authors, instead of one, which has allowed for new approaches and a more critical and synergistic presentation of the material. Every section has been a group effort, with careful editorial inputs from all three of us. In this way, poor-quality images and confusing or nebulous text have been excluded (we hope), and innovative ideas have had a chance to take root and undergo refinement. The images, which are truly the heart and soul of the text, are a dramatic improvement from the first edition, thanks to improved cameras and technology. Several additional sections have been added to capture the latest thinking in nomenclature as well as some of the less common diseases that are entering the mainstream of clinical and pathological practice.

What has not changed is the purpose of the book, which is intended to serve as a primer, an atlas, and a reference text. As a primer, the book reviews very basic information, including hair anatomy and the "nuts and bolts" of processing and evaluating specimens. The authors assume that the reader knows very little about hair disease or hair pathology, and so a stepby- step approach is utilized. As an atlas, the book is rich in photographs demonstrating both basic and advanced histological features of hair disease. As a reference, the book includes the most up-to-date information about the pathology of hair disease, presented with a synopsis format. Basic clinical features are reviewed to provide clinicopathological correlation.

We expect that dermatopathologists will be the most enthusiastic audience for this book. However, many general pathologists and dermatologists were avid users of the first edition, and we expect the same to be true of the second.

LEN

The science of hair pathology has come a long way since Dr. Headington's seminal article on the subject (Headington J. Transverse microscopic anatomy of the human scalp. Arch Dermatol 1984;120:449–56). We still owe Dr. Headington a debt of gratitude; and many of his keen observations are utilized in this text. I have been fortunate to follow the footsteps of many pioneers in the field of hair disease, such as David Whiting, Vera Price, Wilma Bergfeld, Al Solomon, and Rodney Dawber. David Whiting, in particular, has been a selfless mentor and "cheerleader" for much of my work. I have also received support and encouragement from many other leaders in the field of hair disease, such as Jerry Shapiro, George Cotsarelis, Kurt Stenn, Elise Olsen, Amy McMichael, Rodney Sinclair, Lynne Goldberg, Antonella Tosti, Catherine Stefanato, Laila El Shabrawi-Caelen, and Jeffrey Miller.

The confidence to move forward with an ambitious project such as this text is due, in part, to the encouragement I have received from my academic idols and mentors: William D. James, Stephen I. Katz, John Stanley, Kim Yancey, George Lupton, Jeffrey Callen, Jennifer McNiff, and Larry Laughlin, among others.

My co-authors, Shawn Cowper and Eleanor Knopp, are simply brilliant and have brought so much to this endeavor. And of course Joanne and Laura are always there for me. They make the effort worthwhile.

SHAWN

My interest in alopecia comes from "hands on" experience in the alopecia clinic at UCSF, where I worked with Vera Price and her fellow, Paradi Mirmarani. This was bolstered by the excellent dermatopathology training I received from my fellowship mentors Tim McCalmont and Phil Leboit.

Besides these early influences in my academic career, I would like to thank Len, whose work I admired long before I finally got to work with him in 2006. He is a patient and unflappable teacher, and a pragmatic practitioner of evidence-based medicine. I want to thank him not only for his instruction and example, but also for inviting me to be a part of this project— a true team effort created over many months of authoring, imaging, editing, revising, and re-revising.

Our coauthor, Eleanor, is among the kindest and smartest people I have ever met, and I know she will have a truly great career. It has been a pleasure working with her as she made her way through Yale over the years, culminating in the successful completion of her fellowship in dermatopathology virtually coincident with her co-authorship of this second edition.

My wife Carolyn, and our children Nathaniel, Benjamin, and Emma all deserve medals for their patience while this edition came together. I love you all.

I would like to thank our dermatopathology fellow, Ashley Mason, for taking on the proofreading of this text in addition to her many other duties. In addition, thanks to Carol Hribko, whose expertise with image editing and careful proofreading brought this edition to a new standard of excellence. Lastly, I thank my partners at Yale for their support of this effort.

ELEANOR

There are many minds, eyes, and hands that helped create this work. To all who contributed ideas, research, images, and time: thank you.

Len has a knack for making difficult things simple. His knowledge is profound, his thinking is clear, and lucky for the rest of us, he is open and generous with his insights. He has been an incomparable teacher, mentor, and friend, and I am grateful to him for inviting me to contribute to this project.

Shawn is a remarkable physician, an innovator with expertise in diverse areas of dermatopathology, and a phenomenal teacher. Our collaborative "hair service" was a highlight of my dermatopathology education. I feel incredibly fortunate to have trained with Shawn, to count him as a friend, and to have worked together on this project.

I would like to offer my heartfelt gratitude to Jennifer McNiff, Earl Glusac, and the whole team of amazing dermatopathologists at Yale: Rossitza Lazova, Tony Subtil, Christine Ko, Anjela Galan, and Marcus Bosenberg—each has had a profound impact on me. I am enormously thankful for the instruction, guidance, and mentorship from Richard Edelson, Robert Tigelaar, and my Yale Dermatology family.

I am grateful to the North American Hair Research Society and the Women's Dermatologic Society for facilitating my earliest experiences studying under and learning from Len through their mentorship programs. They worked!

I send my love and deepest appreciation to my family, including my father, Robert Knopp, MD, who is missed every moment.

My copy of the first edition of the atlas is well worn and coming apart at the seams—may this edition fare as well in your hands!
