Summary Lichen striatus (LS) is a rare self-limiting inflammatory dermatosis characterized by Blaschkoid distribution. We report a 34-year-old woman with a 1-year history of asymptomatic unilateral rashes on her left trunk and limbs. Physical examination revealed light to dark brown papules, macules, patches and plaques with some erythematous areas in a Blaschkoid pattern with proven skin biopsy as well. Patient received potent topical corticosteroid therapy which resulted in the resolution of the lesion. This case report highlights two rare aspect of lichen striatus; involvement of multiple sites and late adult-onset. It is also a reminder that lichen striatus should be included in the differentials of acquired linear dermatoses.
