The History of this Book
It was a warm day in late July 2002 during the 50th Annual Montagna Symposium on the Biology of Skin when two of us met for the fi rst time. We knew each other longer; the younger part has admired the more experienced part for his pioneer work and great contribution to science, and the latter part was well informed on the scientifi c work of the younger, but they have simply never met before in person. There, in Snowmass, up on the mountains of Colorado, an invitation to lunch was followed by a long exchange of ideas and scientifi c arguments in the fi elds of sebaceous gland, acne, and rosacea that lasted for a few hours. Since then, the two discussants met once a year for lunch during the annual meeting of the Society of Investigative Dermatology and stayed for hours discussing, what else, the developments but also histories on the research of sebaceous gland, acne, and rosacea. They renewed their appointment for the next annual meeting with “a lot of new aspects to elucidate” in between. They even agreed for a common cruise at the islands of Greece in order to have plenty of time for scientifi c discussions under the inspiration of the plain sun and the magic of white and blue. Unfortunately, this journey never took place.

During one of these annual discussions, the experienced part introduced the idea of a book on, what else, the sebaceous gland, acne, and rosacea and motivated the younger part to overtake the task. The latter felt the load too heavy to be carried on his shoulders, especially with all these giants, Albert M. Kligman, Gerd Plewig, and William J. Cunliffe, having overtaken this responsibility before him. But the most experienced insisted: “This volume will be a classic…This will be a great classic, and I am proud to be a part of it…It’s an enormous labor of love for you, but it will do you a great honor when it is fi nished.” So the younger part decided to start the long way, especially with the contribution of a third, politically experienced acneolo-gist, who joined the group and declared: “I have an invitation for a new acne book, would you like us to write it together?” Alea iacta est.
Since then, a few more years have passed; the three editors were accompanied by approximately 100 additional authors from all around the world, hundreds of pages have been written, rewritten, and actualized, and the time for this fi rst edition became mature. It is a great pity that the brain behind the book is not anymore among us to feel proud for the result of the common effort. Dr. Albert Montgomery Kligman died 93-year-old on February 9, 2010, in Philadelphia. He was prophetic regarding the long way to go; the rest two of us can only hope that he will also be prophetic in his prediction that “This volume will be a classic!”
We want to thank all our coauthors for their enormous work and group spirit. We are grateful to Spinger Verlag, especially Mrs. Ellen Blasig, Mrs. Ioanna Panos, and Mr. Sverre Klemp, for their continuous support. We also

thank Dr. Clio Dessinioti for her tireless contribution. And all three of us are indebted to our families for their patience and love.

Introduction
Diseases of facial skin have been mentioned repeatedly in medical history, starting with Greek physicians in antiquity. Hippocrates of Kos and Aristotle in Athens used the term “ίονθοι” (ionthoi, pl.) to describe lesions located on the face as a well-recognised disease appearing during the time when “the fi rst beard grows”, most likely corresponding to what we call acne today. Roman physicians and/or scholars such as Plinius used the term “vari” or “vari seu ionthi” referring to similar skin lesions located in the face, with peaks of oozing and pain. For management honey, soaps, mineral waters and baths, often containing sulphur, were applied in the ancient Roman Empire for cleaning and drying out the skin, as mentioned by Celsus (fi rst century ad ) in his “De Medicina”, a major source of Greco-Roman medicine. Sulphur-containing ointments were still used for the same purpose in Europe during the last centuries, together with laxatives and various diets.
The word “Acne” is obviously derived from the Greek “Ακμή” (acme) and entered the medical literature to indicate a high point, the peak of develop-ment or maturation (of a general condition or disease), as has been used by Galenos from Pergamon (129–201 ad ), though unrelated to skin. During the following centuries, however, this expression came into use also to express the same for an individual, i.e. the fl ourishing period of puberty. It seems that the term took its present signifi cance after having been misspelled in “Ακνή” by the Byzantine physician and medical scholar Aetius Amidanus (502–575 ad ) in writing one of his numerous books (Polybiblia) transferring and com-menting the wisdom of Hippocrates and Galenos . Interestingly, acne is still called “acme” in contemporary Greek medical nomenclature, while the term maintains its original meaning in spoken Greek.
The history of rosacea is less known, although the condition may have been early mentioned by Theocritos in the third century bc , and the fl ushing condition of the face (nose) was later brought in relation to lying and shame. As a medical term “gutta rosacea” was documented by J. Plenck (1735–1807), who separated this entity from “vari” or “ionthi” in classifying cutane-ous diseases, whereas R. Willan (1757–1812) with Th. Bateman (1778–1821) linked rosacea to acne; they listed “acne rosacea” in their nomenclature sys-tem based on clinical morphology, although they recognised the differences.
It seems that C.H. Fuchs , in expressing his disagreement, coined the term “acne vulgaris” (“Die Krankhaften Veränderungen der Haut”, Göttingen, 1840), indicating a disease of facial skin affecting young individuals and

leaving pitted scars, aiming to clearly separate the condition from “acne rosacea”. The specifi c denominations of distinctive clinical phenotypes and variants of acne commonly used today, such as comedonic/papulopustular, conglobate, nodulocystic, acne tarda, androgenica, venenata, etc., were compiled by various authors over the last century.
Why such a comprehensive book on acne and rosacea? In our modern societies skin diseases are most common and due to their
visibility and identifi cation with the suffering individual have reached great attention by the medical community and the public. Acne in particular, with all its variants, is a leading diagnosis in the dermatologist’s offi ce and has become a hot issue in recent years. In European populations over 70–80 % of all males will experience acne in some point of their lifetime. In the USA acne has been reported to affect an estimated number of over 25 (17–45) mil-lion Americans, while spending on topical anti-acne preparations and oral anti acne drugs amounted billions of dollars in recent years.
The presence of acne on the face is visible to all while appearing in early life during a critical phase of individual self-recognition. In addition, some mystery of acne derives from its unclear aetiopathology and its incidence in young boys and girls, obviously in relation with the synthesis of hormones and their precursors in menarche and adrenarche, an imagined relation to sexual activities, and its interaction with the psychological status of the patient during adolescence. Needless to say, there are a series of misconcep-tions referring to the signifi cance of the disease for life quality, but indisput-ably, most of the young patients with acne clearly suffer, some of them having the feeling of being inferior and stigmatised. They all look for understanding and treatment.
Over the past decades thorough laboratory investigations on the piloseba-ceous unit have been performed and a series of possible acnegenic mecha-nisms were elucidated in experimental and clinical models. As a result, both the causes and pathogenesis of acne have become increasingly expanding, complicated issues in part, and diffi cult to overlook. The numerous reasons for developing acne may overlap or even clearly differ from one individual to another. Especially the mechanisms of persisting comedogenesis, the genera-tion of pro- and anti-infl ammatory lipids, the consecutive receptor processing and the intriguing pathways leading to transformation of comedonal, non- infl ammatory, into infl ammatory skin lesions, including the governance of their particular clinical morphology and course, are not fully clarifi ed, being still under ongoing investigation.
The major tissue component involved in the pathogenesis of acne is the sebaceous gland as a mastermind of hormone metabolism and, possibly, hormone synthesis in skin. Hyperseborrhea, hyperkeratinisation of the duct lumina with appearance of microcomedos and insuffi cient comedolysis, bacterial colonisation and infl ammatory tissue response leading to papules, pustules, nodules and cysts are major causes for generating the disease; however, a series of side pathways and the sequence of events involved remain to be elucidated. Hormonal disorders (systemic and/or peripheral hyperandrogenism), inappropriate skin care and hygienic conditions (oily bases and other acnegenic cosmetics), bacteria ( P. acnes, etc.), various

drugs (anticonvulsants, lithium, androgens, anabolic steroids with resting androgenic properties, corticosteroids), toxic agents (chlorinated polyphe-nols), halogens (iodine, chlorine, bromides, etc.), nutrition (fats, seafood, chocolate, nuts, milk products, westernised food with high carbohydrates and diverse relation of ω-unsaturated lipids) and stress (neuropeptides) may all have an infl uence in generating acne lesions, based on genetic predisposition that controls the frequency of infl ammatory lesions, and, possibly, their severity. The question arises as far as genuine infl ammatory mechanisms are contributory factors in acne, with PPAR and stimulated toll-like receptors being primarily involved in its pathogenesis.
Overall, acne may be regarded as a model of a complex cascade of events, controlled by hormones, leading to infl ammation.
Therapy of acne is a challenge in a considerable number of cases, also because disfi guring scars may result and become permanent, if the disease progresses. Individualised treatment is recommended. Therefore, a wide range of anti-acne preparations are of growing signifi cance for the prescrip-tion market, both topical remedies and systemic drugs including antikeratinising and antiseborrhoeic agents, antibacterials, antibiotics, reti-noids, hormones and hormone-like products and various others. Retinoids in particular have revolutionised the treatment of acne, and after its fi rst intro-duction into the market in 1982 isotretinoin has been a global frontrunner. It is still today the most successful drug in the treatment of severe acne, and its worldwide sales were a few years ago at the level of one billion dollars, growing by 5–10 % per year. However, although the anti-acne potency of isotretinoin is unsurpassed, its teratogenicity, among other side effects, is a serious risk that limits its oral use requiring continuing contraception. Recently, an assumed relation of isotretinoin to 5-serotonin metabolism sus-pected to cause depression and suicidal ideation is of additional concern.
Thus, the evolution of acne therapy is still ongoing, and, in addition to further improvement of conventional modalities, new potent anti-acne agents surface, also based on the concept that acne, may represent a genuine infl am-matory disorder per se . Together with new antibiotics and conventional reti-noids, rexinoids, 5α-reductase inhibitors, leukotriene antagonists and 5-lipoxygenase inhibitors are under current investigation. In addition, new therapeutic and managing options are being reported for the practicing der-matologist by using modern technical devices, such as light and UV thera-pies, photodynamic agents, various types of lasers, etc.
The three editors of this comprehensive book represent three generations of prominent dermatologists with profound and long-lasting experiences on acne and rosacea, covering all related clinical and investigational issues. They faced together the challenge to approach and cover the multifactorial issues in several small and specifi c chapters written by an international community of colleagues, all experts in their fi elds. Thus, different aspects and emerging views are presented in this book, summarising our accumulating knowledge. The editorship maintains a red line by having clustered and reviewed the manuscripts. This book has been designed as an indispensable work of refer-ence for all physicians dealing with acne or rosacea and for scientists having specifi c questions on any relevant issue, including the established theories on

the clinical entities covered, their treatment and pathogenesis, while also referring to new concepts and alternative views.
Acne and rosacea is a most interesting fi eld of expanding dermatological research on a series of intriguing scientifi c and clinical mechanisms leading to disfi guring skin lesions. Such a comprehensive textbook epitomises our updated knowledge and current understanding on acne and rosacea.
I sincerely hope that it will also stimulate the fantasy and catalyse the vigour of young dermatologists and researchers, in their attempt to present new evidence on this important section of dermatology, following their own visions.
At the end, the patients who suffer will harvest the real benefi t.
