Dermoscopy in General Dermatology: A Practical Overview

The document from 2016 provides a detailed overview of how dermoscopy, a noninvasive diagnostic tool, is used to identify specific features of a wide range of dermatological conditions, including various forms of alopecia and scalp disorders. It describes the dermoscopic patterns for conditions such as mycosis fungoides, subacute cutaneous lupus erythematosus, classical lichen planus, guttate psoriasis, and different types of alopecia, highlighting key features like fine short linear vessels, Wickham striae, and hair shaft thickness heterogeneity. The document also covers dermoscopic signs for other skin diseases, emphasizing the importance of integrating dermoscopic findings with clinical context for accurate diagnosis. It discusses the choice of dermoscopy equipment and provides levels of evidence for the findings, which range from systematic reviews to case reports and personal observations. The document acknowledges the need for further high-quality studies to better define the role of dermoscopy in general dermatology and notes limitations such as the lack of direct comparative studies for some conditions.
