For dermatology residents and trainees, as well as those in clinical practice, Dermatology is the leading reference for understanding, diagnosing, and treating the full spectrum of skin disease-and is the key resource that residents rely on throughout their training and certification. Widely recognized for its easy-in, easy-out approach, this revised 5th Edition turns complex information into user-friendly visual content through the use of clear, templated chapters, digestible artwork, and easy-to-follow algorithms and tables. This two-volume masterwork provides complete, authoritative coverage of basic science, clinical practice of both adult and pediatric dermatology, dermatopathology, and dermatologic surgery-more than any other source, making it the gold standard reference in the field today. Simplifies complex content in a highly accessible, highly visual manner, with 1,100 tables; 2,600 figures, including numerous disease classification algorithms as well as diagnostic and therapeutic pathways; and over 1,500 additional figures and tables online. Utilizes weighted differential diagnosis tables and a "ladder" approach to therapeutic interventions. Features an intuitive organization and color-coded sections that allow for easy and rapid access to the information you need. Retains an emphasis on clinicopathologic correlations, with photomicrographs demonstrating key histologic findings adjacent to clinical images of the same disorder. Contains updated treatment information throughout, including immune checkpoint inhibitors, JAK inhibitors, and monoclonal antibodies for a wide range of conditions such as psoriasis, atopic dermatitis, alopecia areata, vitiligo, and skin cancers. Provides up-to-date information on genetic and molecular markers and next-generation sequencing as it applies to dermatologists. Features new videos, including cryosurgical and suturing techniques, treatment of rhinophyma via electrosection, and neuromodulator treatment of axillary hyperhidrosis. Includes new WHO classifications of skin tumors, new FDA pregnancy drug labeling, and new ACR/EULAR criteria for vasculitis and lupus erythematosus. Includes new sections on confocal microscopy and artificial intelligence. An eBook version is included with purchase. The eBook allows you to access all of the text, figures, and references, with the ability to search, customize your content, make notes and highlights, and have content read aloud.
