Established for 55 years as the preeminent dermatopathology text, Lever's Histopathology of the Skin is now in its Ninth Edition--thoroughly updated and now illustrated entirely in full color. With contributions from over 50 recognized experts, comprehensive coverage of the histopathologic diagnosis of skin diseases, and up-to-the-minute information on pathogenesis, immunohistochemistry, and contemporary molecular techniques, this text is a must for in-training and practicing dermatologists and pathologists. This edition contains more than 1,300 full-color illustrations, including photomicrographs and new clinical photographs of dermatologic conditions and reaction patterns. 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.
