The Effectiveness of ECP in Diffuse Cutaneous Systemic Sclerosis

The purpose of this study is to assess feasibility, safety and preliminary efficacy of Extracorporeal Photopheresis in the treatment of active diffuse cutaneous systemic sclerosis (dcSSc). This pilot study will help to determine if further study (a RCT) is justified.
