Dermatopathology Diagnosis by First Impression

The atlas that helps you differentiate visually similar diseases

Written with the dermatology trainee in mind, Dermatopathology: Diagnosis by First Impression uses more than 800 high resolution color images to introduce a simple and effective way to defuse the confusion caused by dermatopathology slides. Focused on commonly tested entities, and using low- to high-power views, this atlas emphasizes the key differences between visually similar diseases by using appearance as the starting point for diagnosis.

The Third Edition provides:

• 800 high resolution and annotated photographs, now all fully downloadable
• 'Key Differences' to train the eye on distinctive diagnostic features
• Disease-based as well as alphabetical indexes
• 75 new interactive self-assessment questions to perfect your diagnostic skills
• Brand new algorithms for pattern analysis

Dermatopathology: Diagnosis by First Impression, Third Edition, once again provides simple and effective guidance to help you approach dermatopathology and accurate diagnosis of skin disease.
