Dermatopathology is a specialized branch of pathology in which there has been great progress as new techniques have become available to evaluate the pathology of the skin. Many of the advances in our knowledge and understanding of the skin and the diseases that affect it have been made by people with experience of both diagnostic pathology and clinical dermatology. With significant numbers of large textbooks available, there is a need to provide practical clinical information and concise criteria for pathologic diagnosis for pathologists and dermatologists looking for up-to-date diagnostic and management options.
