Bronchial carcinoma with eosinophilia and cardiomegaly.

A patient with a giant cell carcinoma of the bronchus presented with headache and flushing attacks and a blood eosinophilia. He developed a right bundle branch block and later congestive cardiac failure. At post mortem he was found to have the appearance of Loeffler's endocarditis. A tentative mechanism for these events is proposed.
