Diffuse and Bilateral Lichen Striatus

Abstract

A 5-year-old girl had a papulo-squamous dermatosis arranged in a Blaschko line pattern of 1 month's duration. The skin lesions were asymmetrically distributed bilaterally on the face, neck, trunk, and limbs. Histologically there was a lichenoid infiltrate with foci of spongiosis. The dermatosis cleared spontaneously with hypopigmentation 16 months later. Lichen striatus usually occurs in a solitary and unilateral fashion. Its diffuse and bilateral distribution is an uncommon presentation.
