Lichen sclerosus et atrophicus in a surgical scar treated with fractional laser.

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory disease of unknown cause that typically affects the genital area (1). It has been reported in post-traumatic areas as a result of Koebner phenomenon. LSA responds poorly to treatment making it a therapeutic challenge (2). Laser therapy has been described for LSA with variable results (3,4).
