Abstract:
Lichen sclerosus et atrophicus (LSA) is a rare, chronic, mucocutaneous disease of unknown etiology. Onset can occur in subjects of any age, but the condition is more prevalent in adult females around the time of menopause. In both sexes, the most common site of the lesions is the anogenital area. Bullous lichen sclerosus et atrophicus is an unusual form of the disease and the exact prevalence is not known. We describe a case of nongenital bullous LSA in a man.
