Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>We report the case of a 68‐year‐old woman who underwent heart transplantation for hypertrophic cardiomyopathy. Two months after the transplant she developed mild fever and dyspnea with a marked drop in left ventricle ejection fraction of 31%. Coronary angiography was negative for cardiac allograft vasculopathy. Endomyocardial biopsy revealed ischemic damage with no evidence of acute cellular rejection, antibody‐mediated rejection or viral myocarditis. A neoplastic process was suspected even though full‐body computerized tomography was negative for malignancy. The patient died 4 months after transplantation. The autopsy showed acute antero‐septal myocardial infarction due to a nodular epicardial EBV‐related posttransplant lymphoproliferative disorder (PTLD) infiltrating the left anterior descending coronary artery with occlusive neoplastic thrombosis. We highlight two major aspects of this case: (1) the unusual occurrence of early PTLD involving the cardiac allograft and causing a fatal outcome, (2) the application of an immunological technique for HLA‐DRB1 typing to posttransplant paraffin‐embedded autopsy material to identify the recipient origin of this early malignancy, thus excluding a possible donor‐transmitted neoplasm.</p> </abstract>
