Frontoparietal scleroderma (en coup de sabre) following Blaschko's lines.

We describe three patients with frontoparietal scleroderma showing multiple lesions. The lesions were in two different lines that seemed to belong to Blaschko's lines. It remains controversial whether linear scleroderma follows Blaschko's lines, but our observations presented here suggest that frontoparietal scleroderma occurs along the lines of Blaschko.
