Abstract:
Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory dermatosis presenting as white papules and atrophic patches in the anogenital region. Extragenital LSA is rare and commonly affects the neck, thighs, and the trunk. A 68-year-old woman presented with a well-demarcated, whitish linear plaque on the forehead that was observed several months prior to presentation. A biopsy specimen showed hyperkeratosis and thinning of the epidermis and homogenization of collagen in the papillary dermis with a subepidermal cleft. Mild periappendageal lymphocytic infiltration and eccrine gland atrophy secondary to thickening of collagen bundles were observed in the deep dermis. Based on the clinical and histopathological findings, this patient was diagnosed with extragenital LSA and concomitant morphea along the Blaschko's lines.
