Lichen sclerosus et atrophicus (LSA)is a chronic inflammatory disease with a predilection for the anogenital area. We report a rare case of an 11-year-old girl with extragenital LSA. She presented with hypopigmented pruritic lesions on the chest and upperback since 3 years. A histopathological examination of the back revealed hyperkeratosis with keratotic plugging andliquefaction degeneration in the epidermis as well as edema and sclerosis in the dermis； these findings were compatible with LSA. Partial improvement was shown with topical corticosteroid ointment at the 3-month follow up.
