Dermatopathology: Diagnosis by First Impression, 4th Edition, by Christine J. Ko and Ronald J. Barr, is a pattern-based atlas designed to help dermatopathologists and trainees quickly distinguish between visually similar skin diseases. By emphasizing microscopic patterns rather than disease categories, this atlas equips readers to develop rapid, accurate “first-impression” diagnoses. The book integrates high-resolution photomicrographs with practical guidance, including key differences between similar entities, algorithms, and self-assessment tools, making it an essential reference for both practice and training.
