Scleromyxedema: Successful Treatment of Cutaneous and Neurologic Symptoms

Scleromyxedema is a rare systemic disorder characterized by cutaneous sclerosis and papulosis, accompanied by deposition of mucin in the skin and other organs. We describe a case of scleromyxedema in a 62-year-old man. The cutaneous symptoms of the disorder were preceded by episodes of acute central nervous system dysfunction that included mental confusion, hemiparesis, tremor, and migraine. As the cutaneous symptoms progressed, the patient experienced persistent confusion and difficulty concentrating. Therapy with melphalan and plasmapheresis led to complete resolution of the cutaneous symptoms as well as near-resolution of the neurologic symptoms. This is the first report to describe the successful treatment of the cutaneous symptoms of scleromyxedema accompanied by reversal of chronic neurologic dysfunction.
