Dermoscopy of Lip Lichen Planus—A Descriptive Study

摘要

Isolated lip lichen planus (LP) can mimic lip discoid lupus erythematosus, actinic cheilitis, pemphigus vulgaris, exfoliative cheilitis, and herpes simplex [1]. Dermoscopic features of cutaneous LP have been well-described in the literature, with Wickham striae (WS) as the distinctive feature of an active disease. However, the dermoscopic patterns of lip LP remain to be elucidated. Only a few case reports have reported the dermoscopic patterns of lip LP that include WS: diffuse scaling and violaceous background [1,2]. Herein, we aim to provide new insights into the dermoscopic profile of biopsy-proven cases of lip LP.
