Full-blown graft-versus-host disease presenting with skin manifestations, jaundice and diarrhoea: an unusual paraneoplastic phenomenon of a thymoma.

We describe a patient who presented with chronic diarrhoea, skin lesions and jaundice. Based on histopathological examinations of the affected organs combined with the clinical features, it appeared that the patient fulfilled the criteria for graft-versus-host disease (GVHD). GVHD occurs especially after allogeneic stem cell transplantation and sometimes after organ transplantations.
