Building on a successful first edition, this revised and extended Atlas of Dermoscopy demonstrates the state of the art of how to use dermoscopy to detect and diagnose lesions of the skin, with a special emphasis on malignant skin tumours. With well over 1,500 photographs, drawings, and tables, the book has extensive clinical correlation with dermoscopic images, so readers can appreciate the added benefits of dermoscopy by comparing the clinical morphology seen with the naked eye with the corresponding dermoscopic morphology; extensive illustrations from the image collections of internationally recognized experts, who have years of experience refining their techniques; and extensive schematic drawings to help readers single out the key structures and patterns to recognize in the dermoscopic images. The second edition has important new material on such topics as observed differences between polarized and non-polarized dermoscopy, newly recognized structures and patterns, refined and revised suggestions for pattern analysis, dermoscopy of the hair and nails, and how to integrate dermoscopy into general clinical practice. It also covers dermoscopically equivocal, false negative, and false positive lesions; discusses further indications for dermoscopy beyond skin cancer; and details common checklists of criteria and algorithms used to diagnose skin lesions.
