Thymoma-associated cutaneous graft-versus-host-like reaction

Abstract

A 47‐year‐old man presented with diarrhoea, acquired hypogammaglobulinaemia and a cutaneous graft‐versus‐host‐like reaction in association with a spindle cell thymoma. Graft‐versus‐host reactions usually occur following allogeneic transplantation or transfusion of immunocompetent lymphoid cells but have been described rarely in the context of a thymoma.
