Trauma-induced linear scleroderma

Linear scleroderma (linear morphea) is a form of localized scleroderma characterized by sclerotic lesions distributed in a linear, band-like pattern. Despite its benign course, the disease can cause severe cosmetic, orthopedic, and psychologic problems. The cause is unknown. Many cases are preceded by a history of trauma. We describe a case in which linear scleroderma occurred following a laceration to the affected site. We review the treatment options and discuss the current theories regarding the pathogenesis of the disease.
