a Plurifocal inflammatory infiltrate with myocyte necrosis, consistent with acute lymphocytic myocarditis (a, b hematoxylin and eosin, scale bar 100 micron and 50 micron). Immunostaining for leukocyte marker CD3 showed a number of T lymphocytes > 7/mm2 (scale bar 50 micron). b Focal inflammatory infiltrate with myocyte necrosis, consistent with persistent lymphocytic myocarditis (a, b hematoxylin and eosin, scale bar 100 micron and 50 micron). Immunostaining for leukocyte marker CD3 showed a focus of T lymphocytes < 7/mm2 (scale bar 50 micron)
