Dermoscopy is a critical tool in the evaluation of pigmented lesions, but understanding the wide array of patterns can be confusing, especially to the novice. This book presents a concise, organized approach to dermoscopy. The early chapters orient the clinician to the use of the scopes and typical images produced with oil immersion. The second chapter outlines the distinct patterns, ie, radial streaming, blue white veil, and psuedopods. The authors discuss the relative specificity and sensitivity of these patterns in relation to the diagnosis of melanoma vs dysplastic nevi and pigmented basal cell carcinoma. Most important, they provide a visual comparison of the dermoscopy image, the clinical presentation, and the histopathology. The later chapters in the book are devoted to specific lesions including melanocytic nevi, melanoma, and nonmelanocytic pigmented tumors. Each subject is presented with an extensive array of dermoscopic images covering almost every pattern variation. The melanoma chapter is very comprehensive, and tables are used to outline the microscopic features of melanoma. There are also tables that summarize the critical points when evaluating basal cell carcinomas and seborreic keratoses vs melanocytic lesions.
