Bilateral linear lichen planus along the lines of Blaschko: Report of a rare case and brief review
Journal Title: Nasza Dermatologia Online - Year 2017, Vol 8, Issue 3
Abstract
Linear lichen planus (LP) is a rare variant of lichen planus that may present in a dermatomal or zosteriform distribution or develop along the lines of Blaschko. Blaschkoid linear LP is a rarer distinct variant of LP and should be differentiated from other linear subtypes of LP and other Blaschkoid dermatoses. A 24-year-old male patient presented with multiple shiny, purple, polygonal papules arranged perpendicularly over the right lower extremity and also in shorter curvilinear (S-shaped) lesions on the left side of the abdomen and left flank along the lines of Blaschko. The histopathological findings of a biopsy specimen were compatible with the clinical diagnosis of lichen planus. To date, almost all of the reported cases of linear lichen planus along the lines of Blaschko have had unilateral presentations. We herein report a rare case of bilateral linear Blaschkoid lichen planus and review the literature briefly.
