Myocardial histology from a 31-year-old male competitive athlete who died suddenly as first manifestation of arrhythmogenic cardiomyopathy. Autopsy revealed biventricular arrhythmogenic cardiomyopathy and evidence of myocardial inflammation: (A) subepicardial fibrofatty replacement of the left ventricular free wall (Trichrome stain); (B) abnormal cardiomyocytes with dysmorphic nuclei, replacement fibrosis and inflammatory infiltrates with myocytolysis (arrow); (C) immunotyping for macrophages (CD68 antibody); (D) immunotyping for T lymphocytes (CD3 antibody).
