The purpose of this book is to outline the topics that are critical in the dermatological approach to patients with cancer. This purpose will be accomplished by discussing the value of a multidisciplinary approach, and case examples will be used, including some from the Hospital Sírio-Libanês, a pioneering institution in the treatment of cancer. In all, the book will present and discuss the best global evidence for the dermatologic care of patients with cancer, skin cancer, and solid organ- and bone-marrow-transplanted patients. The clinical, surgical, pathologic, imaging, radiotherapy, oncology and palliative care aspects of the dermatologic care of cancer patients will be covered. The book will also discuss subjects such as genetics, biology, evidence-based medicine, and new diagnostic methods and tools such as dermoscopy and confocal microscopy. Chapters will be based on the following key areas: educating clinicians on how to prevent skin cancer in patients, screening and counseling, diagnosis and treatment of pigmented lesions, melanoma and nonmelanoma skin cancer, cutaneous lymphomas, sarcomas, leukemic and lymphomatous infiltrations, cutaneous metastases, cutaneous paraneoplasic manifestations and cutaneous adverse reactions to chemotherapy and radiation treatment. The primary audiences are dermatologists, oncologists, radioncologists and oncologic surgeons. The secondary audience is residents in these fields. The goal is to prepare and update all specialists on this important clinical and research area.
