Linear Lichen Planus: Two Case Reports

Özet

Lichen planus (LP) is an idiopathic inflammatory skin disease which affects the skin, mucosa, nails, and hairsof middle-aged individuals. Linear lichen planus (LLP) is a rare variant of LP characterized by pruritic, lichenoidappearance, violaceous-color papules in a linear pattern. About 0.24 to 0.62% of patients with LP have beenreported to have LLP. In cases with LP, linear lesions can be post-traumatically seen as widespread generalizederuptions (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 anyprevious association with trauma or herpes infection. Herein, we present two cases with LLP and emphasizethe rarity of these cases and the importance of linear lesions in the differential diagnosis.
