A 9-year-old girl had a grayish pigmented macule on the right ankle for a year ago. Three months ago, she noticed depigmented lesions on her ankle surrounding the pigmented macule. The depigmented spots were lined continuously to the right patella along the Blaschko’s line. Histopathological examination of the lesion revealed typical features of lichen sclerosus et atrophicus. The lesions were ameliorated by topical treatment with glucocorticoid and vitamin D3 ointments.
