The dynamic nature of the medical sciences presents a constant challenge for the dermatologist, but the past 25 years have necessitated a shift in approach to the profession. With the increasing influx of biological data, and developments in diagnostic and treatment techniques, our armamentarium has expanded to treat an increasing number of pathologies and enabled the vast advancement in corrective procedures. In addition, the recent prevalence of tumor pathologiesin particular, the tumors of the skinhas resulted in a growing number of patients to seek out the dermatologist for treatment. Dermatologists are now required to continually update their knowledge of and techniques in dermatological surgery. As many as 350 pathologies can now be treated by surgery. Also dermatologists are now dealing with an increasing number of cosmetic surgery treatments, which require the use of several devices (eg, lasers, ultrasounds, and radiofrequencies, etc.). Such high-tech devices, and their evident biological action, can only be properly used by dermatologists after having acquired the proper expertise. Many countries all over the world have developed communities: national societies, conferences, and educational outlets, to address these surgical topics. This textbook was written in the spirit of these dermatological communities; as a tool to improve surgical knowledge and technique; and, mostly, to assist the dermatologist in meeting the rising medical needs of todays patient.
