Scleromyxedema with dermato-neuro syndrome.

Scleromyxedema is a rare connective tissue disease of unknown cause characterized by a generalized papular eruption, dermal fibroblast proliferation, and monoclonal paraproteinemia. A paroxysmal triad consisting of high fever, seizures, and coma with a flu-like prodrome can rarely occur in patients with scleromyxedema and is termed "dermato-neuro syndrome." We describe a 41-year-old patient with scleromyxedema in whom the dermato-neuro syndrome developed.
