Abstract
Over the last few years, dermoscopy has been increasingly used in the field of inflammatory diseases, such as papulosquamous disorders, vasculitis, autoimmune diseases, and inherited diseases. According to the most recent consensus of the International Dermoscopy Society, the main dermoscopic finding categories are as follows: vessels (morphology, distribution), scales (color, distribution), follicular findings, other structures (color, distribution), and specific clues. Vessel morphologic types can be dotted, linear, linear with branches, or linear curved. Vessel distribution can be uniform, clustered, peripheral, reticular, or nonspecific. Scale color can be white, yellow, or brown. Scale distribution can be diffuse, central, peripheral, or patchy. Follicular findings include follicular plugs, follicular red dots, perifollicular white color, and perifollicular pigmentation. Other structure categories include color (white, brown, gray, blue, orange, yellow, or purple) and morphology (structureless areas, dots/globules, lines, or circles). Specific clues include Wickham striae (lichen planus (LP)), peripheral keratotic structures with two free edges (porokeratosis), and spongiotic vesicles (eczema). Of note, the diagnosis of inflammatory diseases should not be based on only dermoscopic examination findings. A combination of clinical history and macroscopic, dermoscopic, and even histopathological examination findings is needed to reach the final diagnosis.
