Hourglass shaped extragenital Csillag’s disease

Lichen sclerosus (LS) is a benign, chronic inflammatory dermatosis affecting both the epidermis and dermis. It commonly affects the anogenital area and is seen predominantly in women. In only 15–20% of cases, extragenital involvement is seen. In females, long-standing anogenital lesions progress to form hourglass or dumbbell or figure of eight morphology. Here, we are reporting a case of extragenital LS at an unusual site in an hourglass morphology, which is usually encountered in females. Our patient was started on ultrapotent topical corticosteroids, following which erythema was reduced. The patient is advised regular follow-up.
