Extragenital Lichen Sclerosus Et Atrophicus Masquerading as Discoid Lupus Erythematosus

Abstract

Lichen sclerosis et atrophicus is rare chronic inflammatory dermatoses of unknown yet multifactorial etiology. The disease tends to affect the anogenital region either alone or in combination with other areas. Extragenital areas are affected in the form of depressed and atrophic, whitish macule or plaques. The lesions tend to affect the upper half of the trunk, neck and upper limbs. We are reporting a case of 45 years old female patient who presented with multiple hypopigmented to depigmented plaques with hyperpigmented border over the anterior, posterior and lateral aspect of both legs since five years associated with moderate grade itching. Dermoscopic examination shows homogenous white areas with mixed blood vessels. Histopathology examination showed features suggestive of lichen sclerosis et atrophicus. This case has been reported for its rarity and atypical presentation.
