We describe a very rare case of bilateral lichen striatus on the lower extremities with a history of more than ten years. Histopathologically, the lesions demonstrated a lichenoid tissue reaction with foci of spongiosis and perivascular inflammatory cell infiltration. In addition, the finding of lymphocytic infiltrations around the eccrine duct was observed. They were treated successfully with topical application of corticosteroid ointment. To the best of our knowledge, no other lichen striatus case has been reported with bilateral distribution and such long-term persistence.
