Lichen Planus

Chapter

Abstract

Lichen planus is a chronic, inflammatory, itchy skin disorder of unknown origin. The dermatoscopic clue is represented by the detection of Wickham striae, which mainly appear as pearly white, yellowish, or blue-white structures of variable shapes, with a reticular arrangement being the most common one. Active lesions often show dotted, globular, and/or linear vessels mainly distributed at the periphery, while regressing lesions feature pigmented structures, such as dots, globules, and/or reticular or cloud-like areas. Hypertrophic lichen planus and lichen planus pigmentosus may show distinctive dermatoscopic findings, i.e., comedo-like structures/corn pearls and brownish-grayish peppering over a brown background, respectively.
