Frontal linear scleroderma (also known as en coup de sabre or morphea en coup de sabre) is a type of linear scleroderma characterized by a linear band of atrophy and a furrow in the skin that occurs in the frontal or frontoparietal scalp.[1][2] Multiple lesions of en coup de sabre may coexist in a single patient, with one report suggesting that the lesions followed Blaschko's lines.[3] It gets its name from the perceived similarity to a sabre wound.[4]
