Abstract

Dermoscopy is increasingly used by clinicians (dermatologists, family physicians, podiatrists, doctors of osteopathic medicine, etc) to inform clinical management decisions. Dermoscopic findings or images provided to pathologists offer important insight into the clinician's diagnostic and management thought process. However, with limited dermoscopic training in dermatopathology, dermoscopic descriptions and images provided in the requisition form provide little value to pathologists. Most dermoscopic structures have direct histopathologic correlates, and therefore dermoscopy can act as an excellent communication bridge between the clinician and the pathologist. In the first article in this continuing medical education series, we review dermoscopic features and their histopathologic correlates.
