Weedon’s Skin Pathology Cutaneous biopsies and excisions constitute the most frequently performed procedures in surgical pathology, yet they present some of the most difficult diagnostic challenges. Through five authoritative editions, Weedon’s Skin Pathology has earned outstanding reviews and accolades from practicing and trainee dermatopathologists, general pathologists, and dermatologists worldwide. The 6th Edition continues this tradition of excellence, helping you accurately and efficiently sign out complex skin cases in everyday practice, while also keeping you up to date with recent advances in the field. Dr. James W. Patterson’s single-author approach continues to provide clarity and consistency from cover to cover, resulting in what has been described as “the best reference text available in dermatopathology in the world” (Pathology).

• Provides comprehensive coverage of the full spectrum of dermatopathological entities, both inflammatory and neoplastic, highlighted by more than 1,800 color photomicrographs that illustrate the full range of pathologic appearances and help identify each diagnostic entity.
• Helps you arrive at the most accurate diagnoses possible by demonstrating what is seen through the microscope and identifying the characteristic features of the lesion―for established disorders, unusual and rare disease entities, and incompletely defined entities.
• Includes new information on molecular diagnostics throughout, including FISH (fluorescence in situ hybridization) techniques, plus new developments in molecular biology and molecular techniques, targeted-personalized medicine, and immunohistochemistry.
• Contains more tables for quick reference, new figures that demonstrate key differential diagnostic points, and discussions of new entities, as well as thorough content updates in every section.
• Includes practical advice on diagnostic pitfalls and how to avoid them to help minimize reporting errors, and diagnostic clues to assist both experienced and novice practitioners in formulating an accurate diagnosis.
• Identifies both important articles and more rare and unusual reports with remarkably authoritative, comprehensive, current, and relevant reference lists (over 35,000) for each entity.
