Cutaneous Chronic Graft Versus Host Disease Following Allogeneic Haematopoietic Stem Cell Transplantation in Children: A Retrospective Study

Abstract

Chronic graft versus host disease (cGVHD) is a complication of allogeneic haematopoietic stem cell transplantation (HSCT). The aim of this study was to clinically characterize childhood cutaneous cGVHD. A retrospective study of children treated with HSCT at 2 tertiary medical centres in Israel between 2011 and 2014 was performed. A total of 112 children were included. Cutaneous cGVHD developed in 18% of subjects. Risk factors were older age, HSCT from peripheral blood and acute lymphoblastic leukaemia. The eruption was lichenoid in 90% of subjects, of whom one-third progressed to sclerosis. Topical treatments were usually sufficient in localized disease. Widespread eruption necessitated phototherapy, extracorporeal photopheresis and/or systemic immunosuppressants. Patients presenting with palmoplantar keratoderma, developed sclerosis. To the best of our knowledge, this is the first study describing childhood cutaneous cGVHD. Lichenoid eruption is the most common cutaneous pattern of cGVHD in children. Sclerotic changes may be associated with prior keratoderma. cGVHD poses a therapeutic challenge and better treatments should be sought.
