Review of the previous edition: "This book presents hundreds of dermatoscopic color images of melanoma, nevi, and non-melanoma skin cancers. The objective is to teach readers how to recognize a skin malignancy by training the eye to scan for the major pertinent criteria. This is an essential skill for all dermatologists to master." --Patricia Wong, MD (Private Practice) Doody's Review Service
