Extrapulmonary oat-cell carcinoma presenting as a primary left ventricular tumor: A case report

An asymptomatic 57-year-old man had an abnormal resting electrocardiogram and a positive treadmill stress test. Cardiac catheterization with left ventriculography revealed a large left ventricular mass in the apex, but otherwise normal coronary arteries. Excisional biopsy of the mass was consistent with oat-cell carcinoma. Additional evaluation was negative for metastasis. The patient was treated with combined chemoradiotherapy and was doing well at 16 months follow-up. (Heart Lung® 2002;31:229-32.)
