Background: Linear scleroderma has been associated with muscle spasms ipsilateral to skin lesions. Typically, spasms are located in trigeminal innervated muscles, leading to hemimasticatory spasm (HMS). Case Report: We report a case of linear scleroderma associated with spasm of muscles innervated not only by the trigeminal but also by the facial nerve. Discussion: We review the patient's successful treatment with incobotulinumtoxinA, a formulation of botulinum toxin that has not been reported for use in this condition.
