A combination chemotherapy for myeloma induced dramatic improvement of the skin lesions in accordance with a marked decrease in serum IgA levels as well as the disappearance of circulating anti-intercellular IgA autoantibodies, suggesting a pathogenetic link between skin lesions and IgA-κ paraprotein produced by myeloma ce
