Painful linear atrophic lichen planus along lines of Blaschko

Linear lichen planus along the lines of Blaschko is uncommon. Atrophic lichen planus is usually a sequel to resolving annular and ulcerative lesions. We herewith report a case of histopathologically proven lichen planus, presenting with atrophy at the outset, in a linear distribution along the lines of Blaschko. In addition to the cutaneous findings, she also had pain along the distribution of lesions.
