We report the case of a 46-year-old male who developed dermatomyositis and a sarcoid-like reaction in association with testicular relapse of multiple myeloma. The myositis progressed despite chemotherapy directed at the underlying malignant disorder and immunosuppressive treatment. There was, however, a dramatic and sustained response to high-dose chemotherapy and autologous peripheral blood stem cell transplantation which resulted in resolution of the myopathy and partial resolution of the sarcoid-like reaction. This case report highlights the potential of autologous stem cell transplantation as treatment for para-neoplastic disorders associated with haematological malignancies.
