A tri-linear pattern of scleroderma 'en coup de sabre' following Blaschko's lines

Linear scleroderma 'en coup de sabre' is characterized by atrophy and furro wing of the skin of the frontoparietal region. In most cases it occurs as a single, paramedian line that may be associated with hypoplasia of underlyi ng structures and hemiatrophy of the face. Rarely, lesions form two lines, either both on the same side or bilaterally. We describe an 18-year-old mal e with an unusual tri-linear pattern of scleroderma 'en coup de sabre' foll owing Blaschko's lines.
