Myocardial Sarcoidosis With A Tumor‐Like Left Atrial Thrombus

We report here an elderly woman who started vague complaints around the age of 50, was proved to be a sarcoidosis by negative skin reaction with purified protein derivative, bilateral hilar lymphadenopathy, and sarcoid lesions in biopsied liver and lymph nodes, and died of cardiac insufficiency after 15 years of the illness. Necropsy revealed a huge tumor‐ like left atrial thrombus with nonspecific fibrous lesions throughout the myocardium, a pulmonary hamartoma, pneumonia, liver cell necrosis, and cholecystopathy. To our knowledge, this may be the first case of myocardial sarcoidosis associated with this kind of atrial thrombus, although the sarcoidosis and thrombus may have occurred independently.
