The aetiology of GAVE is unknown, but it is associated with several conditions including autoimmune disease, chronic renal failure and liver disorders. It can also develop as a complication of haematopoietic stem cell transplantation (HSCT)-GAVE, most associated with conditioning regimens including busulfan. HSCT-GAVE has also been linked with thrombotic microangiopathy and graft versus host disease (GVHD), but the relationship is poorly understood. This report presents a patient status post-allogeneic HSCT who developed severe refractory GAVE, ultimately found to be a manifestation of liver GVHD responsive to treatment with
