Early onset of scleromyxedema Arndt-Gottron associated with a monoclonal gammapathy: Successful treatment with intravenous immunoglobulins.

Arndt-Gottron (S-AG) syndrome or scleromyxedema is a scarce disease characterized by a generalized papular and sclerodermoid eruption and systemic manifestations that can lead to significant morbid-mortality. Interesting, S-AG can be associated with a paraprotein. We report an exceptional scleromyxedema case associated with a benign monoclonal gammapathy in an old woman.
