Lichen striatus is a fairly common, linear, self-limited eruption that is seen primarily in children. The average age is 3 years, but it can occur at any age. In adults, lichen striatus often presents a quit different clinical feature rather than in childhood. It is characterized by papulovesicles, multilinearity, relapse, and histological spongiotic change. We report two cases of lichen striatus occured in a 45-year-old and 32-year-old man.
