Lichen simplex chronicus secondary to scald injury and skin flap transplantation

Abstract

A 50-year-old woman had suffered from chronic pruritic plaque located on right retroauricular area for around 16 years, which was diagnosed as lichen simplex chronicus. Seventeen years ago, patient had multiple scalded areas distributed throughout the body and underwent autologous skin flap transplantation for the right retroauricular wound. After the wound healed, patient started experiencing paresthesia continuously on the skin grafted area and could not resist scratching. To our knowledge, this is the first reported case of lichen simplex chronicus secondary to scald injury and skin flap transplantation. We successfully treated this patient with dyclonine hydrochloride cream 1% and desonide cream 0.05%.
