title: Unilateral trachyonychia in a patient with reflex sympathetic dystrophy.
abstract: Reflex sympathetic dystrophy (RSD) is a poorly understood neurovascular disorder characterized by pain, altered sensation, motor disturbance, soft tissue changes, vasomotor changes, and autonomic changes that occurs after trauma to an extremity. Unilateral leukonychia, Beau's lines, nailfold swelling, and nail clubbing have been an observed sequela of RSD. We present a case of a unilateral atypical trachyonychia occurring in the setting of RSD after traumatic fracture of a digit.
