Organ transplantation has been successfully performed over the last 35 years and the number of organ allograft recipients is steadily increasing. Long-term immunosuppression, necessary for good graft function, inevitably induces undesired effects (particularly infectious and neoplastic ones) among which cutaneous ones are very frequent and potentially life-threatening. This book deals with all aspects of cutaneous disorders that may be encountered in the setting of organ transplantation. It reflects the pioneering work performed since long by Dermatologists in Lyon, in collaboration with teams specialised in kidney, heart, lung, liver and pancreas transplantation.
