Linear Lichen Sclerosus along the Blaschko's Line of the Face

ABSTRACT

Lichen sclerosus et atrophicus (LSA) is an inflammatory disease that primarily causes anogenital lesion in middle aged women. We present here a case of facial LSA with an asymptomatic, well-demarcated, whitish to bluish, atrophic patch in a linear pattern on the forehead of a 48-year-old woman. This case showed an atypical clinical presentation and it mimicked en coup de sabre, but the histopathologic results confirmed the diagnosis of LSA.
