Spectacular and Prompt Response to Extracorporeal Photopheresis for Refractory Cutaneous Chronic Graft-Versus-Host Disease after Allogeneic Hematopoietic Stem Cell Transplantation: A Case Report

Chronic graft-versus-host disease (cGVHD) is a serious complication after allogenic hematopoietic stem cell transplantation (allo-HSCT), negatively affecting the morbidity and mortality of recipients. Skin involvement is the most common cGVHD manifestation with a wide range of pleomorphic features, from scleroderma to ulcerations and microangiopathic changes. Despite the access to many immunosuppressive drugs, therapy for cGVHD is challenging. Systemic steroids are recommended as the first-line treatment; but, in steroid-resistant patients, extracorporeal photopheresis (ECP) remains one of the subsequent therapeutic options. Here, we present a case report of a 31-year patient suffering from advanced steroid-refractory skin and oral mucosa cGVHD who was spectacularly treated with ECP. It was the first time we observed such “overnight” resolution of the graft-versus-host disease syndrome. The present report proves the important role of ECP in the treatment of steroid-resistant cGVHD, especially when other immunosuppressive therapies have failed.
