Bullous pemphigoid associated with acute graft-versus-host disease after allogeneic bone marrow transplantation.

A 47-year-old patient was treated with allogeneic bone marrow transplantation (BMT) for chronic myelogenous leukaemia in blast crisis. Three months after the procedure he developed bullous pemphigoid (BP) and symptoms suggestive of BP oesophageal involvement, associated with skin and liver acute graft-versus-host disease. The occurrence of BP is exceptional after BMT.
