title: Intralesional steroid-therapy-induced reduction of plasma interleukin-6 and improvement of cutaneous plasmacytosis.
abstract: We describe a case of primary multiple cutaneous plasmacytosis successfully treated by intralesional steroid therapy. Plasma interleukin-6 (IL-6) levels reduced in parallel with the disease activity. Intralesional steroid reduced IL-6 production by peripheral blood mononuclear cells, while neither PUVA therapy nor intralesional recombinant interferon-gamma resulted in a benefit and plasma IL-6 levels did not decrease. It was suggested that IL-6 might play an important role in the pathogenesis of this condition.
