Lever's Histopathology of the Skin is a classic, comprehensive work that has been used by generations of dermatopathologists, pathologists, and dermatologists to further their knowledge, in their current practices, and in the training of their students. The pathophysiologic organization is based on Walter Lever's original scheme, with appropriate modifications over the years, and is more efficient than the pattern method, since related entities are discussed in juxtaposition. This edition contains over 1,400 full-color illustrations, including photomicrographs and clinical photographs of diseases not covered in previous editions. The chapter on algorithmic pattern recognition has been expanded and extensively cross-referenced to the chapters on diseases to aid readers in generating differential diagnoses for unknown cases.
