Abstract: Dermoscopy is an aiding method in the visualization of the epidermis and dermis. It is usually used to diagnose melanocytic lesions. In recent years, dermoscopy has increasingly been used to diagnose non-melanocytic lesions. Certain vascular structures, their patterns of arrangement and additional criteria may demonstrate lesion-specific characteristics. In this review, vascular structures and their arrangements are discussed separately in the light of conflicting views and an overview of recent literature.

“…This is because it has been suggested that most of the inflammatory diseases may display dotted vessels of variable diameter and there is no indication that categorization by diameter could have any diagnostic significance when using low‐magnification (handheld) dermoscopes . Dotted vessels histologically correspond to the tips of vertically arranged, dilated vessels in dermal papillae and were initially described as a typical finding of psoriasis (Fig. a), but subsequent studies have shown that they can be found in many other inflammatory dermatoses (e.g.…”

“…Characteristic dermoscopic features of amelanotic malignant melanoma are "polymorphous vessels and milky red areas" and those of basal cell carcinoma are "arborizing vessels". 7,8 We think that the large red/blue globules in pink ovoid nests in our case may be a characteristic dermoscopic finding specific to EMPSGC.…”

“…Cutaneous microvessels that arborize into thin red branches in a nonhomogeneous fashion were considered as nonspecific dermoscopic findings because they are also common in normal skin. Given that dermoscopy enables horizontal inspection of the skin, vessels that run parallel to the skin surface are visualized as lines, whereas those that run perpendicularly are generally viewed as dots, or even loops . However, they are best evaluated when the pressure exerted by the dermoscope against the skin is low.…”

High outside pressure may indeed reduce blood flow in cutaneous capillaries.…”
