Lichen striatus is a self-limiting dermatosis presenting with sudden eruption of lichenoid papules along the lines of Blaschko. A 5-year-old girl presented with asymptomatic hypopigmented linear lesions over both upper limbs. The histopathological examination revealed spongiosis, vacuolar alteration of the basal layer and lymphocytic exocytosis with a mild-to-moderate perivascular mononuclear infiltrate in the dermis. Lichen striatus was diagnosed based upon the characteristic clinical and histopathological findings. The pathogenetic mechanism of bilateral lichen striatus is unknown at present, however, a somatic mutation in two different clones of cells can be a possibility.
