Based on extensive clinical, histological, and experimental studies, this guide serves as an authoritative source of information on the epidemiology, etiology, pathogenesis, diagnosis, and treatment of cutaneous lymphomas-reflecting the state-of-the-art in the field of cutaneous lymphomas-presented in the context of the brand-new WHO/EORTC-consensus-classification.

Anergic reactions and anergic diseases are found in many fields of medicine. As wen as affecting the skin, allergic diseases occur in internal organs such as the lungs and the kidneys and in the vascular and nervous systems. Interdisciplinary understanding and cooperation thus seem necessary to get a better insight into allergic reactions in the different fields of medicine in order that we may give our patients the best diagnostic and therapeutic care. Allergic diseases are on the increase. Studies from Sweden show that 15% of the population there are atopic, and some people speculate that in Germany about 10%-15% of all adults suffer from one of the many different allergic conditions. We in our clinic also have the impression that the incidence of atopic reactions has increased in recent years. The figure of 15% would mean something like 200 000 people in Munich alone We all know that a wide variety of environmental factors can induce allergic reactions in the skin, the respiratory system, or internal organs. The most important anergens in our environment are pollen, molds, animal dander, housedust mite, food or food additives, various insects, industrial compounds and drugs. The direct costs of hospital and community medical care, other services, and drugs to help patients with asthma, hay fever, and skin allergies have in creased considerably in the last 10 years. The figures should make it clear to everybody that we are dealing with a health and environmental problem of great practical importance."

Recent progress in the fields of pharmacology and immunology has provided us with new possibilities for treating dermatological diseases. This book reviews the most important immunosuppressive and immunostimulatory drugs and gives helpful, practical information on the treatment of various dermatoses, including autoimmundiseases, atopic dermatitis, psoriasis, vasculitis, contact dermatitis, pyoderma gangrenosum, infectious diseases, and neoplasms of the skin - in particular, malignant melanoma.

From the first to the third of August, 1980, an international sym posium entitled "New Trends in Allergy" was held in Munich, sponsored by the Ludwig-Maximilian University, Munich, in cooperation with the German Society for Allergy and Immunity Research and the European Society for Dermatological Research. The symposium pursued two main goals: to bring allergy oriented colleagues from various specialties such as dermatology, otorhinolaryngology, pediatrics, internal medicine, immunology, and pulmonology together for interdisciplinary contacts and dis cussions; and to attract internationally known experts in an effort to disseminate information on new and fundamental develop ments in allergology. The fact that English has become the lingua franca at congresses for the exchange of ideas in medical specialties led to the decision to hold the symposium in English. In spite of the mild handicap this posed for some participants, it was also a major factor in the symposium's success. This book contains the papers delivered by the invited speakers together with the poster presentations. They cover both basic ex perimental research as well as clinical problems in allergology."

Die in den letzten Jahren zunehmende Inzidenz des malignen Melanoms hat diesen b-sartigsten Tumor der Haut vermehrt in den Vordergrund des Interesses der Dermato-Onkologie ger}ckt. Besondere Beachtung verdienen in diesem Zusammenhang neue therapeutische M-glichkeiten mit Interferon undInterleukin als Immunmodulatoren. Die Besch{ftigung hiermit ist ein wesentlicher thematischer Bestandteil des Buches. Dar}ber hinaus werden Besonderheiten von Hauttumoren bei Jugendlichen und bei alten Patienten er-rtert.

H. Kresbach (Tagungsleiter), Graz Zunachst allen Teilnehmern unseren herzlichen Gruss Retikulumzellen bezieht und weder dem lymphati und Dank dafur, dass sie der Einladung der Universitats schen noch dem mononuklearen Phagozystensystem klinik fur Dermatologie und Venerologie in Graz zu zugeordnet werden kann, ist damit fragwurdig gewor diesem Symposion zu Ehren unseres hochgeschatzten den. Begriffe wie "maligne Retikulose" oder, Retiku Jubilars em. Univ. -Prof. Dr. Anton Musger in so grosser losarkom" der Haut konnen mit Hilfe moderner Me Zahl gefolgt sind. Mein besonderer Gruss gilt den Her thoden heute weiter differenziert werden und sind ren Referenten aus dem In- und Ausland. Wir sind sehr jedenfalls nicht mehr als Entitaten anzusehen. Auch die sog. Retikulosarkomatose Gottron bedarf heute glucklich, heute so viele fuhrende Vertreter der deutsch keiner Sonderstellung mehr. Nach eigenen Erfahrungen sprachigen Dermatologie als massgebliche Mitgestalter handelt es sich dabei z. T. um immunoblastische Lym unseres Symposions bei uns zu wissen. Mit der Wahl des Themas wollten wir einerseits der wissenschaftli phome. "Erythrodermatische Retikulosen" haben sich chen Tatigkeit unseres Jubilars eine Reverenz erweisen inzwischen in den meisten Fallen als T-Zell-Lymphome und andererseits der uberaus grossen Aktualitat des herausgestellt. Gegenstandes Rechnung tragen. Beurteilung und Klassifikation lymphoretikularer Trotz aller Einwande und unter Berucksichtigung Neoplasien der Haut haben sich in den letzten Jahren der zeitbedingten Bezogenheit von Irrtum und Wahr entscheidend geandert."
