A North American perspective on dermoscopy: benefits, limitations, and grey zones.

Dermoscopy offers novel and cost-effective diagnostic information to guide patient care for melanocytic and non-melanocytic dermatoses. This article reviews the current use of dermoscopy, including its clinical benefits and limitations. Surveys of U.S. and Canadian dermatology residents have demonstrated a desire for improved dermoscopy teaching; an abundance of evidence calls for increasing its use in the clinical setting. Using the current evidence framework, North American dermatology training centers and professional societies should work to foster dermoscopy training and use by both dermatologists and other health care providers.
