Abstract
Lichen sclerosus et atrophicans (LSA) is an idiopathic inflammatory dermatosis. It mainly affects the anogenital area. Extragenital sites are affected rarely in isolation. It presents as ivory or porcelain-white, shiny, round macules or papules, coalescing to form sclerotic plaques with prominent dilated pilosebaceous or sweat duct orifices. Histopathology is indicated to differentiate it from previtiligo, morphea, and atrophic lichen planus. There is no known cure for LSA. Standard treatment modality includes topical corticosteroid and calcineurin inhibitors, such as tacrolimus. We report a case of a middle-aged man with isolated extragenital LSA.
