Over the last decades the incidence of skin cancers is dramatically increasing world-wide. This is not only confined to the incidence of melanoma but includes also other skin cancers such as basal cell carcinomas. Based on the recent WHO classification of skin cancers, this lavishly illustrated reference book covers comprehensively the epidemiology, histology and pathology, as well as diagnostic signs and treatment options of skin cancers. Homogenously and reader-friendly structured, it links the diagnostic and genetic features of each disease in order to guide the reader to the most appropriate therapeutic strategies for the best possible treatment outcome. In order to demonstrate the world wide activities in the field, all chapters cover the variations of the individual experiences and expertise in different nations.

Professor Reinhard Dummer leads a team of ca. 15 practitioners at the Department of Dermatology, University of Zurich Hospital.  He is board certified in dermatology and allergology and clinical immunology. His research includes in particular the immune biology of cutaneous lymphomas, cutaneous melanomas, and epithelial skin cancers, and this research has led to immune interventions in cell cultures and animal models and to translational research. He is the author of more than 300 original articles and is a recognized opinion leader in cutaneous oncology worldwide. Professor Dummer is past president of the International Society for Cutaneous Lymphomas, a board member of the European Association for Dermatological Oncology, and past president for the European Society for Dermatological Research.

 

Mark Pittelkow is a Professor of Dermatology at the Mayo Clinic, Rochester, USA and is board certified by the American Board of Dermatology. His research interests are broad and include cutaneous T-cell lymphoma, cutaneous carcinoma, and especially melanoma. He is a member of the Mayo Clinic Melanoma Study Group. Professor Pittelkow is the author of numerous scientific articles on diverse aspects of dermatology.

 

Professor Keiji Iwatsuki graduated from Hokkaido University School of Medicine and received his PhD from Hamamatsu University School of Medicine, Japan. He is Professor and Chairman of the Department of Dermatology, Okayama University Graduate School of Medicine and Dentistry. His research interests include virus-related lymphomas and autoimmune diseases and he has an impressive publication record.

Adele Green is Professor of Epidemiology in the Epithelial Sciences Research Group, School of Translational Medicine, University of Manchester; Deputy Director, Queensland Institute of Medical Research (QIMR), Brisbane, Australia; and Head, Population and Cancer Studies Unit, QIMR. She also holds Professorships at the University of Queensland and Griffith University. In 2004 she was named in the Australian Honours List as a Companion of the Order of Australia. She has served on many Australian research bodies and has also been a chair or member of many committees at the International Agency for Research on Cancer in  Lyon, France. Her main area of interest is cancer epidemiology, with a particular focus on melanoma and other skin cancers.

Nagwa M. Elwan is Professor of Dermatology at the Faculty of Medicine, Tanta University, Egypt. She is a member of the Egyptian Society of Dermatology, the American Academy of Dermatology, the American Society of Dermatopathology, the International Society of Dermatopathology, and the International Society for Cutaneous Lymphoma. Professor Elwan is the author of more than 50 research articles on dermatopathology, acne, psoriasis, atopic dermatitis, lymphoma, and leprosy and has been guest speaker at many national and international dermatology meetings.
