[Cardiac sarcoidosis with multinucleated giant cells detected in endomyocardial biopsy specimens: report of 3 cases].

This is a report of 3 cases of cardiac sarcoidosis. None of the 3 patients had other overt systemic involvement. Multinucleated giant cells and non-caseating epithelial cell granulomas with small lymphocytic infiltrations were detected in the endomyocardial biopsy specimen. Some focal left ventricular wall motion abnormalities were detected by echocardiography and angiography in all 3 patients. Paroxysmal ventricular tachycardia and multifocal ventricular premature complexes were observed by Holter 24-hour electrocardiography in all 3 patients. Two of the 3 patients did not receive corticosteroids, but remaining patient is on a regimen of corticosteroid.
