A unilateral linear pattern of lichen planus pigmentosus: a case report

Abstract

Lichen planus pigmentosus (LPP) is a rare chronic variant of lichen planus (LP). The distribution of LPP tends to be symmetric and frequently seen on the face, neck, and truck. Atypical clinical patterns of LPP including segmental, zosteriform and linear were reported in the literature. Herein, we report here a rare presentation of LPP in a 16-year-old female with a unilateral linear pattern along the blascko lines.
