The present report describes a patient with cardiac sarcoidosis who developed complete right bundle branch block, complete atrioventricular block and subsequent congestive heart failure. The patient demonstrated no clinical evidence of systemic sarcoidosis. Upon postmortem examination, the myocardium showed extensive noncaseating granuloma with numerous multinucleated giant cells. An initial routine microscopic examination of the lung revealed no evidence of granulomatous lesions. However, an extensive microscopic examination of the lung using serial sections demonstrated inconspicuous granulomatous lesions with giant cells. Thereby, a diagnosis of sarcoidosis was made. All other organs were free of granulomatous inflammation in spite of an extensive microscopic examination through serial sections. The present case suggests that a careful and extensive microscopic examination of the other organs may be necessary to establish a diagnosis of cardiac sarcoidosis.
