Lichen planus is a chronic, heterogeneous, inflammatory dermatosis occurring in middle-aged adults. It can affect the skin, mucous membranes, and dander. The pathophysiology involves an immune reaction mediated by T lymphocytes, which attack basal keratinocytes, inducing apoptosis. Dermoscopy is a non-invasive examination enabling the visualization of structures invisible to the naked eye, located at the epidermis, the dermo-epidermal junction, and the dermis. In this article, we describe the dermoscopic aspects of lichen planus and its topographic variants.
