Extragenital lichen sclerosus et atrophicus within a skin graft scar

Lichen sclerosus et atrophicus (LSA) is rare chronic relapsing skin condition typically arising in postmenopausal women and prepubescent children in the genital area. Only 6% of cases occur in extragenital skin without concomitant anogenital involvement.1 LSA can exhibit the Koebner phenomenon. Although various types of inciting events have been documented for the development of extragenital lichen sclerosus et atrophicus, we present the first case, to our knowledge, to occur within a skin graft donor site.
