Dermoscopy is a useful tool for finding and screening skin tumors, especially skin cancers. It is well known that it is useful to diagnose pigmented tumors, such as melanocytic lesions. In recent years, after the publication of a revised two-step algorithm in 2010, dermoscopy gradually has been used to diagnose non-pigmented or non-melanocytic lesions based on their vascular structures. Some skin lesions have specific vascular structures that aid in diagnosis. In this review, I discuss the various patterns of the vascular structures and their distribution, focusing on their clinical importance and usefulness in daily medical treatment.
