Abstract
ABSTRACT
Observation:
Lichen sclerosus et atrophicus is a chronic, inflammatory dermatosis that is characterized by pruritic, white, atrophic plaques. It classically affects the anogenital region of postmenopausal women. Extragenital involvement also may occur with several reported morphologic variants. Extragenital bullous lichen sclerosus et atrophicus is a rare variant, which presents as flaccid bullae. It favors the trunk and proximal aspects of the extremities. We describe a 58-year-old woman with a six month history of extragenital lichen sclerosus et atrophicus, who developed a bullous eruption within a pre-existing patch of lichen sclerosis on the lower back.
