It has been both an honor and a challenge to serve as the author of The Netter Collection： Integumentary System. I am honored to have contributed to the legacy that The Netter Collection so deserves with its timeless quality and continued contribution to medical education. Of course， the challenge was in determining that which would and should be included in the volume， in keeping with the tradition of relevance of the series. My hope is that this volume is appreciated by those with vast experience as well as those individuals just beginning their journey of lifelong learning， which I feel so accurately describes the medical world.
　　My sincerest gratitude is extended to people behind the scenes at Elsevier， specifically Marybeth Thiel， as well as the artists who were able to bring the slightest nuance to life for the benefit of clinician and patient alike. Although no volume exclusively dedicated to the integumentary system existed， I attempted to incorporate as many of Frank Netter's depictions as possible. In several instances however， this simply was not possible， and I therefore had the pleasure and privilege of working with Carlos Machado， MD， and Tiffany S. DaVanzo， MA， CMI， whose talent deserves to be formally recognized. Their artwork captures the subtleties of the integumentary system. For that I am forever grateful.
　　I would like to thank all those who have positively influenced， taught， and mentored me， specifically， Jeffrey Miller， MD， Warren Heymann， MD， the late John Stang， MD， and James Marks， MD-your impact on my career has been immeasurable. Certainly， this list is not exhaustive. I have had the pleasure of crossing paths with so many fine people-sadly， too many to list. A special thank you goes to Ruth Howe and Cheryl Hermanson， whose help was simply incredible； I truly appreciate all you did. Additionally， I would like to thank my colleagues at the Milton S. Hershey Medical Center， whose encouragement and support have always been a part of our culture.
　　Finally， I would like to recognize and express appreciation for my family： my parents， sisters， Uncle Lou， and my loving Grandmother Ermandina. Your encouragement and support is the foundation from which I draw my confidence to tackle a project such as this. At the time of this writing， my wife， Susan， is in a select group of people who have read， literally， every word of text in this volume. I cannot thank Susan enough for her supportive nature， patience， and love； you are the gem of my life. Lastly， I need to acknowledge my daughters， Rachel and Sarah， of whom I am so proud. The sacrifice of your evenings for more than a year so that I could work in an environment that was productive and conducive to concentration will forever be appreciated.
