Marked and sustained improvement of systemic sclerosis following polychemotherapy for coexistent multiple myeloma

We present the case of a patient who had systemic sclerosis (SSc) with progressive cutaneous and pulmonary involvement and a coexisting monoclonal gammopathy which gradually progressed to overt multiple myeloma. Strikingly, successful VMCP (vincristine, melphalan, cyclophosphamide and prednisolone) polychemotherapy for myeloma was accompanied by a marked and sustained improvement of SSc that has persisted for 2 years after chemotherapy. Most noticeable was a substantial skin softening in our patient, with a > 50% reduction in the skin thickness score following VMCP treatment. Our case suggests that polychemotherapy may represent a promising treatment option in patients with SSc who are refractory to available treatments.
