Lichen sclerosus et atrophicus (LSA) is a rare, chronic, mucocutaneous disease of unknown cause. Onset can occur in subjects of any age but more prevalent in adult females around the time of menopause. In both the sexes anogenital involvement is more common. Extragenital cases are rare, and common localizations are neck and shoulders, axilla, upper arms, flexor aspects of wrists and around the umbilicus. Bullous LSA is an unusual manifestation of the disease. Isolated extragenital bullous LSA is a distinctly rare event with very few cases reported till date.
硬化萎缩性苔藓（LSA）是一种病因不明的罕见慢性黏膜皮肤疾病。任何年龄的人都可能发病，但在绝经前后的成年女性中更为常见。男女两性的肛门生殖器受累更为常见。生殖器外病例罕见，常见部位为颈部、肩部、腋窝、上臂、手腕屈侧和脐周。大疱性LSA是该疾病的一种不寻常表现。孤立的生殖器外大疱性LSA是一种极为罕见的情况，迄今为止报道的病例很少。
