Lichen Simplex Chronicus as the Initial Manifestation of Intramedullary Neoplasm and Syringomyelia

Abstract
Neurogenic causes of pruritus and a rash are uncommon. We report a patient with dermatomal pruritus and a rash who had a cervicothoracic syrinx and a thoracic spinal cord tumor. We believe the syrinx interrupted fibers subserving itch, resulting in dermatomal pruritus with secondary scratching and a rash.
