[Generalized sarcoidosis with a predominant lesion of the myocardium].

Materials on heart sarcoidosis are presented on the basis of the literature analysis, morphological and electron microscopical examination of an autopsy observation. Heart sarcoidosis is characterized morphologically by granulomatous myocarditis with diffuse infiltration with lymphoid and macrophage cells, and marked destructive changes in muscle fibers. A damaging effect of the infiltrate cells on cardiomyocytes is shown.
