Bullous lichen sclerosus et atrophicus: treatment by tangential excision

The bullous variant of lichen sclerosus et atrophicus (LSA) is a rare disorder for which there is no satisfactory treatment. A patient is reported with extensive plaques of bullous LSA on the pretibial skin that did not respond to sharp debridement, vigorous local care, or intralesional corticosteroid injections. Tangential partial-thickness excision of diseased tissues resulted in an extended remission. To our knowledge this approach has not been previously employed for bullous LSA, and it offers an encouraging surgical alternative to other therapeutic modalities.
