A number of congenital and acquired dermatological diseases are known to follow lines of Blaschko. Lichen Planus (LP), commonly acquired inflammatory dermatosis, presents with various morphological forms but Blaschkoian variant is very less published in literature. We herein report a case series of six patients of various age groups with Blaschkoian LP, without any underlying predisposing factors. All these cases presented with asymptomatic to mildly pruritic, violaceous to hyperpigmented papules and plaques following the Blaschko lines. In all the patients, lesions responded well to topical steroids and oral antihistamines, leading to gradual resolution of lesions with post-inflammatory hyperpigmentation. Blaschkoian LP is not a rare condition and may remain under reported because of its insignificant clinical features especially the absence of pruritus. Thus, the physician should always keep this entity in mind while considering the lesions following lines of blaschko.
