Lichen planus (LP) is an idiopathic inflammatory skin disease which affects the skin, mucosa, nails, and hairs of middle-aged individuals. Linear lichen planus (LLP) is a rare variant of LP characterized by pruritic, lichenoid appearance, violaceous-color papules in a linear pattern. About 0.24 to 0.62% of patients with LP have been reported to have LLP. In cases with LP, linear lesions can be post-traumatically seen as widespread generalized eruptions (Koebner phenomenon) and as zosteriforms on herpes infection as the Wolf's isotopic response. However, LLP indicates the presence of spontaneous LLP lesions which follow Blaschko's lines without any previous association with trauma or herpes infection. Herein, we present two cases with LLP and emphasize the rarity of these cases and the importance of linear lesions in the differential diagnosis.
