RESUMO
Scleromyxedema is a chronic, idiopathic disorder associated with monoclonal gammopathy, and characterized by dermal mucin deposition. However, systemic manifestations are frequent, including neuromuscular symptoms. We herein present a 71-year-old man who developed a vacuolar myopathy in a context of a known scleromyxedema, and we compare our observation with the nineteen other cases found in the medical literature. Such an association (especially with suggestive skin abnormalities) has to be known for two reasons. First, this diagnosis might be quite challenging because the myopathy may precede the typical skin changes. Secondly, conversely to other forms of vacuolar myopathy, some of the symptoms may respond (even partially) to immunomodulatory and/or immunosuppressant therapeutics.
